- * The bootstrap method may elect to produce call sites of a

- * An {@code invokedynamic} instruction which has not yet been executed
- * is said to be <em>unlinked</em>.  When an unlinked call site is executed,
- * the containing class's bootstrap method is called to manufacture a call site,
- * for the instruction.  If the bootstrap method does not assign a non-null
- * value to the new call site's target variable, the method {@link #initialTarget}
- * is called to produce the new call site's first target method.
- * <p>
- * A freshly-created {@code CallSite} object is not yet in a linked state.
- * An unlinked {@code CallSite} object reports null for its {@code callerClass}.
- * When the JVM receives a {@code CallSite} object from a bootstrap method,
- * it first ensures that its target is non-null and of the correct type.
- * The JVM then links the {@code CallSite} object to the call site instruction,
- * enabling the {@code callerClass} to return the class in which the instruction occurs.
- * <p>
- * Next, the JVM links the instruction to the {@code CallSite}, at which point
- * any further execution of the {@code invokedynamic} instruction implicitly
- * invokes the current target of the {@code CallSite} object.
- * After this two-way linkage, both the instruction and the {@code CallSite}
- * object are said to be linked.
- * <p>
- * This state of linkage continues until the method containing the
- * dynamic call site is garbage collected, or the dynamic call site
- * is invalidated by an explicit request.
+ * A call site may be <em>relinked</em> by changing its target.
+ * The new target must be non-null and must have the same
+ * {@linkplain MethodHandle#type() type}
+ * as the previous target.
+ * Thus, though a call site can be relinked to a series of

-/**
- * A Java method handle is a deprecated proposal for extending
- * the basic method handle type with additional
- * programmer defined methods and fields.
- * Its behavior as a method handle is determined at instance creation time,
- * by providing the new instance with an "entry point" method handle
- * to handle calls.  This entry point must accept a leading argument
- * whose type is the Java method handle itself or a supertype, and the
- * entry point is always called with the Java method handle itself as
- * the first argument.  This is similar to ordinary virtual methods, which also
- * accept the receiver object {@code this} as an implicit leading argument.
- * The {@code MethodType} of the Java method handle is the same as that
- * of the entry point method handle, with the leading parameter type
- * omitted.
- * <p>
- * Here is an example of usage, creating a hybrid object/functional datum:
- * <p><blockquote><pre>
- * class Greeter extends JavaMethodHandle {
- *     private String greeting = "hello";
- *     public void setGreeting(String s) { greeting = s; }
- *     public void run() { System.out.println(greeting+", "+greetee); }
- *     private final String greetee;
- *     Greeter(String greetee) {
- *         super(RUN); // alternatively, super("run")
- *         this.greetee = greetee;
- *     }
- *     // the entry point function is computed once:
- *     private static final MethodHandle RUN
- *         = MethodHandles.lookup().findVirtual(Greeter.class, "run",
- *               MethodType.make(void.class));
- * }
- * // class Main { public static void main(String... av) { ...
- * Greeter greeter = new Greeter("world");
- * greeter.run();  // prints "hello, world"
- * // Statically typed method handle invocation (most direct):

- * </pre></blockquote>
- * <p>
- * In the example of {@code Greeter}, the method {@code run} provides the entry point.
- * The entry point need not be a constant value; it may be independently
- * computed in each call to the constructor.  The entry point does not
- * even need to be a method on the {@code Greeter} class, though
- * that is the typical case.
- * <p>
- * The entry point may also be provided symbolically, in which case the the
- * {@code JavaMethodHandle} constructor performs the lookup of the entry point.
- * This makes it possible to use {@code JavaMethodHandle} to create an anonymous
- * inner class:
- * <p><blockquote><pre>
- * // We can also do this with symbolic names and/or inner classes:
- * MethodHandles.invokeExact(new JavaMethodHandle("yow") {
- *     void yow() { System.out.println("yow, world"); }
- * });
- * </pre></blockquote>
- * <p>
- * Here is similar lower-level code which works in terms of a bound method handle.
- * <p><blockquote><pre>
- *     class Greeter {
- *         public void run() { System.out.println("hello, "+greetee); }
- *         private final String greetee;
- *         Greeter(String greetee) { this.greetee = greetee; }
- *         // the entry point function is computed once:
- *         private static final MethodHandle RUN
- *             = MethodHandles.findVirtual(Greeter.class, "run",
- *                   MethodType.make(void.class));
- *     }
- *     // class Main { public static void main(String... av) { ...
- *     Greeter greeter = new Greeter("world");
- *     greeter.run();  // prints "hello, world"
- *     MethodHandle mh = MethodHanndles.insertArgument(Greeter.RUN, 0, greeter);
- *     mh.invokeExact();  // also prints "hello, world"
- * </pre></blockquote>
- * Note that the method handle must be separately created as a view on the base object.
- * This increases footprint, complexity, and dynamic indirections.
- * <p>
- * Here is a pure functional value expressed most concisely as an anonymous inner class:
- * <p><blockquote><pre>
- *     // class Main { public static void main(String... av) { ...
- *     final String greetee = "world";
- *     MethodHandle greeter = new JavaMethodHandle("run") {
- *         private void run() { System.out.println("hello, "+greetee); }
- *     }
- *     greeter.invokeExact();  // prints "hello, world"
- * </pre></blockquote>
- * <p>
- * Here is an abstract parameterized lvalue, efficiently expressed as a subtype of MethodHandle,
- * and instantiated as an anonymous class.  The data structure is a handle to 1-D array,
- * with a specialized index type (long).  It is created by inner class, and uses
- * signature-polymorphic APIs throughout.
- * <p><blockquote><pre>
- *     abstract class AssignableMethodHandle extends JavaMethodHandle {
- *       private final MethodHandle setter;
- *       public MethodHandle setter() { return setter; }
- *       public AssignableMethodHandle(String get, String set) {
- *         super(get);
- *         MethodType getType = this.type();
- *         MethodType setType = getType.insertParameterType(getType.parameterCount(), getType.returnType()).changeReturnType(void.class);
- *         this.setter = MethodHandles.publicLookup().bind(this, set, setType);
- *       }
- *     }
- *     // class Main { public static void main(String... av) { ...
- *     final Number[] stuff = { 123, 456 };
- *     AssignableMethodHandle stuffPtr = new AssignableMethodHandle("get", "set") {
- *         public Number get(long i)           { return stuff[(int)i]; }
- *         public void   set(long i, Object x) {        stuff[(int)i] = x; }
- *     }
- *     int x = (Integer) stuffPtr.&lt;Number&gt;invokeExact(1L);  // 456
- *     stuffPtr.setter().&lt;void&gt;invokeExact(0L, (Number) 789);  // replaces 123 with 789

-     * available at the time of the constructor invocation,
-     * due to the rules of Java and the JVM verifier.
-     * One cannot call {@code this.getClass()}, because
-     * the value of {@code this} is inaccessible at the point
-     * of the constructor call.  (Changing this would require
-     * change to the Java language, verifiers, and compilers.)
-     * In particular, this constructor allows {@code JavaMethodHandle}s
-     * to be created in combination with the anonymous inner class syntax.
-     * @param entryPointName the name of the entry point method
-     * @param type (optional) the desired type of the method handle

  *
+ * <h2><a name="bsm"></a>Bootstrap Methods</h2>
+ * Before the JVM can execute a dynamic call site (an {@code invokedynamic} instruction),
+ * the call site must first be <em>linked</em>.
+ * Linking is accomplished by calling a <em>bootstrap method</em>
+ * which is given the static information content of the call site,
+ * and which must produce a {@link java.dyn.MethodHandle method handle}
+ * that gives the behavior of the call site.
+ * <p>
+ * Each {@code invokedynamic} instruction statically specifies its own
+ * bootstrap method as a constant pool reference.
+ * The constant pool reference also specifies the call site's name and type signature,
+ * just like {@code invokevirtual} and the other invoke instructions.
+ * <p>
+ * Linking starts with resolving the constant pool entry for the
+ * bootstrap method, and resolving a {@link java.dyn.MethodType MethodType} object for
+ * the type signature of the dynamic call site.
+ * This resolution process may trigger class loading.
+ * It may therefore throw an error if a class fails to load.
+ * This error becomes the abnormal termination of the dynamic
+ * call site execution.
+ * Linkage does not trigger class initialization.
+ * <p>
+ * Next, the bootstrap method call is started, with four values being stacked:
+ * <ul>
+ * <li>a {@code MethodHandle}, the resolved bootstrap method itself </li>
+ * <li>a {@code Class}, the <em>caller class</em> in which dynamic call site occurs </li>
+ * <li>a {@code String}, the method name mentioned in the call site </li>
+ * <li>a {@code MethodType}, the resolved type signature of the call </li>
+ * </ul>
+ * The method handle is then applied to the other values as if by
+ * {@linkplain java.dyn.MethodHandle#invokeGeneric the <code>invokeGeneric</code> method}.
+ * The returned result must be a {@link java.dyn.CallSite CallSite}, a {@link java.dyn.MethodHandle MethodHandle},
+ * or another {@link java.dyn.MethodHandleProvider MethodHandleProvider} value.
+ * The method {@linkplain java.dyn.MethodHandleProvider#asMethodHandle asMethodHandle}
+ * is then called on the returned value.  The result of that second
+ * call is the {@code MethodHandle} which becomes the
+ * permanent binding for the dynamic call site.
+ * That method handle's type must be exactly equal to the type
+ * derived from the dynamic call site signature and passed to
+ * the bootstrap method.
+ * <p>
+ * After resolution, the linkage process may fail in a variety of ways.
+ * All failures are reported by an {@link java.dyn.InvokeDynamicBootstrapError InvokeDynamicBootstrapError},
+ * which is thrown as the abnormal termination of the dynamic call
+ * site execution.
+ * The following circumstances will cause this:
+ * <ul>
+ * <li>the bootstrap method invocation completes abnormally </li>
+ * <li>the result from the bootstrap invocation is not a reference to
+ *     an object of type {@link java.dyn.MethodHandleProvider MethodHandleProvider} </li>
+ * <li>the call to {@code asMethodHandle} completes abnormally </li>
+ * <li>the call to {@code asMethodHandle} fails to return a reference to
+ *     an object of type {@link java.dyn.MethodHandle MethodHandle} </li>
+ * <li>the method handle produced by {@code asMethodHandle} does not have
+ *     the expected {@code MethodType} </li>
+ * </ul>
+ * <h3>timing of linkage</h3>
+ * A dynamic call site is linked just before its first execution.
+ * The bootstrap method call implementing the linkage occurs within
+ * a thread that is attempting a first execution.
+ * <p>
+ * If there are several such threads, the JVM picks one thread
+ * and runs the bootstrap method while the others wait for the
+ * invocation to terminate normally or abnormally.
+ * <p>
+ * After a bootstrap method is called and a method handle target
+ * successfully extracted, the JVM attempts to link the instruction
+ * being executed to the target method handle.
+ * This may fail if there has been intervening linkage
+ * or invalidation event for the same instruction.
+ * If such a failure occurs, the dynamic call site must be
+ * re-executed from the beginning, either re-linking it
+ * (if it has been invalidated) or invoking the target
+ * (if it the instruction has been linked by some other means).
+ * <p>
+ * If the instruction is linked successfully, the target method
+ * handle is invoked to complete the instruction execution.
+ * The state of linkage continues until the method containing the
+ * dynamic call site is garbage collected, or the dynamic call site
+ * is invalidated by an explicit request,
+ * such as {@link java.dyn.Linkage#invalidateCallerClass Linkage.invalidateCallerClass}.
+ * <p>
+ * In an application which requires dynamic call sites with individually
+ * mutable behaviors, their bootstrap methods should produce distinct
+ * {@link java.dyn.CallSite CallSite} objects, one for each linkage request.
+ * <p>
+ * If a class containing {@code invokedynamic} instructions
+ * is {@linkplain java.dyn.Linkage#invalidateCallerClass(Class) invalidated},
+ * subsequent execution of those {@code invokedynamic} instructions
+ * will require linking.
+ * It is as if they had never been executed in the first place.
+ * (However, invalidation does not cause constant pool entries to be
+ * resolved a second time.)
+ * <p>
+ * Invalidation events and bootstrap method calls for a particular
+ * dynamic call site are globally ordered relative to each other.
+ * When an invokedynamic instruction is invalidated, if there is
+ * simultaneously a bootstrap method invocation in process
+ * (in the same thread or a different thread), the result
+ * eventually returned must not be used to link the call site.
+ * Put another way, when a call site is invalidated, its
+ * subsequent linkage (if any) must be performed by a bootstrap method
+ * call initiated after the invalidation occurred.
+ * <p>
+ * If several threads simultaneously execute a bootstrap method for a single dynamic
+ * call site, the JVM must choose one target object and installs it visibly to
+ * all threads.  Any other bootstrap method calls are allowed to complete, but their
+ * results are ignored, and their dynamic call site invocations proceed with the originally
+ * chosen target object.
+ * <p>
+ * The JVM is free to duplicate dynamic call sites.
+ * This means that, even if a class contains just one {@code invokedynamic}
+ * instruction, its bootstrap method may be executed several times,
+ * once for each duplicate.  Thus, bootstrap method code should not
+ * assume an exclusive one-to-one correspondence between particular occurrences
+ * of {@code invokedynamic} bytecodes in class files and linkage events.
+ * <p>
+ * In principle, each individual execution of an {@code invokedynamic}
+ * instruction could be deemed (by a conforming implementation) to be a separate
+ * duplicate, requiring its own execution of the bootstrap method.
+ * However, implementations are expected to perform code duplication
+ * (if at all) in order to improve performance, not make it worse.

-/**
- * An asynchronous channel for datagram-oriented sockets.
- *
- * <p> An asynchronous datagram channel is created by invoking one of the {@link
- * #open open} methods defined by this class. It is not possible to create a channel
- * for an arbitrary, pre-existing datagram socket. A newly-created asynchronous
- * datagram channel is open but not connected. It need not be connected in order
- * for the {@link #send send} and {@link #receive receive} methods to be used.
- * A datagram channel may be connected, by invoking its {@link #connect connect}
- * method, in order to avoid the overhead of the security checks that are otherwise
- * performed as part of every send and receive operation when a security manager
- * is set. The channel must be connected in order to use the {@link #read read}
- * and {@link #write write} methods, since those methods do not accept or return
- * socket addresses. Once connected, an asynchronous datagram channel remains
- * connected until it is disconnected or closed.
- *
- * <p> Socket options are configured using the {@link #setOption(SocketOption,Object)
- * setOption} method. An asynchronous datagram channel to an Internet Protocol
- * (IP) socket supports the following options:
- * <blockquote>
- * <table border>
- *   <tr>
- *     <th>Option Name</th>
- *     <th>Description</th>
- *   </tr>
- *   <tr>
- *     <td> {@link java.net.StandardSocketOption#SO_SNDBUF SO_SNDBUF} </td>
- *     <td> The size of the socket send buffer </td>
- *   </tr>
- *   <tr>
- *     <td> {@link java.net.StandardSocketOption#SO_RCVBUF SO_RCVBUF} </td>
- *     <td> The size of the socket receive buffer </td>
- *   </tr>
- *   <tr>
- *     <td> {@link java.net.StandardSocketOption#SO_REUSEADDR SO_REUSEADDR} </td>
- *     <td> Re-use address </td>
- *   </tr>
- *   <tr>
- *     <td> {@link java.net.StandardSocketOption#SO_BROADCAST SO_BROADCAST} </td>
- *     <td> Allow transmission of broadcast datagrams </td>
- *   </tr>
- *   <tr>
- *     <td> {@link java.net.StandardSocketOption#IP_TOS IP_TOS} </td>
- *     <td> The Type of Service (ToS) octet in the Internet Protocol (IP) header </td>
- *   </tr>
- *   <tr>
- *     <td> {@link java.net.StandardSocketOption#IP_MULTICAST_IF IP_MULTICAST_IF} </td>
- *     <td> The network interface for Internet Protocol (IP) multicast datagrams </td>
- *   </tr>
- *   <tr>
- *     <td> {@link java.net.StandardSocketOption#IP_MULTICAST_TTL
- *       IP_MULTICAST_TTL} </td>
- *     <td> The <em>time-to-live</em> for Internet Protocol (IP) multicast
- *       datagrams </td>
- *   </tr>
- *   <tr>
- *     <td> {@link java.net.StandardSocketOption#IP_MULTICAST_LOOP
- *       IP_MULTICAST_LOOP} </td>
- *     <td> Loopback for Internet Protocol (IP) multicast datagrams </td>
- *   </tr>
- * </table>
- * </blockquote>
- * Additional (implementation specific) options may also be supported.
- *
- * <p> Asynchronous datagram channels allow more than one read/receive and
- * write/send to be oustanding at any given time.
- *
- * <p> <b>Usage Example:</b>
- * <pre>
- *  final AsynchronousDatagramChannel dc = AsynchronousDatagramChannel.open()
- *      .bind(new InetSocketAddress(4000));
- *
- *  // print the source address of all packets that we receive
- *  dc.receive(buffer, buffer, new CompletionHandler&lt;SocketAddress,ByteBuffer&gt;() {
- *      public void completed(SocketAddress sa, ByteBuffer buffer) {
- *          System.out.println(sa);
- *          buffer.clear();
- *          dc.receive(buffer, buffer, this);
- *      }
- *      public void failed(Throwable exc, ByteBuffer buffer) {
- *          ...
- *      }
- *  });
- * </pre>

+/**
+ * A Java method handle is a deprecated proposal for extending
+ * the basic method handle type with additional
+ * programmer defined methods and fields.
+ * Its behavior as a method handle is determined at instance creation time,
+ * by providing the new instance with an "entry point" method handle
+ * to handle calls.  This entry point must accept a leading argument
+ * whose type is the Java method handle itself or a supertype, and the
+ * entry point is always called with the Java method handle itself as
+ * the first argument.  This is similar to ordinary virtual methods, which also
+ * accept the receiver object {@code this} as an implicit leading argument.
+ * The {@code MethodType} of the Java method handle is the same as that
+ * of the entry point method handle, with the leading parameter type
+ * omitted.
+ * <p>
+ * Here is an example of usage, creating a hybrid object/functional datum:
+ * <p><blockquote><pre>
+ * class Greeter extends JavaMethodHandle {
+ *     private String greeting = "hello";
+ *     public void setGreeting(String s) { greeting = s; }
+ *     public void run() { System.out.println(greeting+", "+greetee); }
+ *     private final String greetee;
+ *     Greeter(String greetee) {
+ *         super(RUN); // alternatively, super("run")
+ *         this.greetee = greetee;
+ *     }
+ *     // the entry point function is computed once:
+ *     private static final MethodHandle RUN
+ *         = MethodHandles.lookup().findVirtual(Greeter.class, "run",
+ *               MethodType.make(void.class));
+ * }
+ * // class Main { public static void main(String... av) { ...
+ * Greeter greeter = new Greeter("world");
+ * greeter.run();  // prints "hello, world"
+ * // Statically typed method handle invocation (most direct):
+ * MethodHandle mh = greeter;
+ * mh.&lt;void&gt;invokeExact();  // also prints "hello, world"
+ * // Dynamically typed method handle invocation:
+ * MethodHandles.invokeExact(greeter);  // also prints "hello, world"
+ * greeter.setGreeting("howdy");
+ * mh.invokeExact();  // prints "howdy, world" (object-like mutable behavior)
+ * </pre></blockquote>
+ * <p>
+ * In the example of {@code Greeter}, the method {@code run} provides the entry point.
+ * The entry point need not be a constant value; it may be independently
+ * computed in each call to the constructor.  The entry point does not
+ * even need to be a method on the {@code Greeter} class, though
+ * that is the typical case.
+ * <p>
+ * The entry point may also be provided symbolically, in which case the the
+ * {@code JavaMethodHandle} constructor performs the lookup of the entry point.
+ * This makes it possible to use {@code JavaMethodHandle} to create an anonymous
+ * inner class:
+ * <p><blockquote><pre>
+ * // We can also do this with symbolic names and/or inner classes:
+ * MethodHandles.invokeExact(new JavaMethodHandle("yow") {
+ *     void yow() { System.out.println("yow, world"); }
+ * });
+ * </pre></blockquote>
+ * <p>
+ * Here is similar lower-level code which works in terms of a bound method handle.
+ * <p><blockquote><pre>
+ *     class Greeter {
+ *         public void run() { System.out.println("hello, "+greetee); }
+ *         private final String greetee;
+ *         Greeter(String greetee) { this.greetee = greetee; }
+ *         // the entry point function is computed once:
+ *         private static final MethodHandle RUN
+ *             = MethodHandles.findVirtual(Greeter.class, "run",
+ *                   MethodType.make(void.class));
+ *     }
+ *     // class Main { public static void main(String... av) { ...
+ *     Greeter greeter = new Greeter("world");
+ *     greeter.run();  // prints "hello, world"
+ *     MethodHandle mh = MethodHanndles.insertArgument(Greeter.RUN, 0, greeter);
+ *     mh.invokeExact();  // also prints "hello, world"
+ * </pre></blockquote>
+ * Note that the method handle must be separately created as a view on the base object.
+ * This increases footprint, complexity, and dynamic indirections.
+ * <p>
+ * Here is a pure functional value expressed most concisely as an anonymous inner class:
+ * <p><blockquote><pre>
+ *     // class Main { public static void main(String... av) { ...
+ *     final String greetee = "world";
+ *     MethodHandle greeter = new JavaMethodHandle("run") {
+ *         private void run() { System.out.println("hello, "+greetee); }
+ *     }
+ *     greeter.invokeExact();  // prints "hello, world"
+ * </pre></blockquote>
+ * <p>
+ * Here is an abstract parameterized lvalue, efficiently expressed as a subtype of MethodHandle,
+ * and instantiated as an anonymous class.  The data structure is a handle to 1-D array,
+ * with a specialized index type (long).  It is created by inner class, and uses
+ * signature-polymorphic APIs throughout.
+ * <p><blockquote><pre>
+ *     abstract class AssignableMethodHandle extends JavaMethodHandle {
+ *       private final MethodHandle setter;
+ *       public MethodHandle setter() { return setter; }
+ *       public AssignableMethodHandle(String get, String set) {
+ *         super(get);
+ *         MethodType getType = this.type();
+ *         MethodType setType = getType.insertParameterType(getType.parameterCount(), getType.returnType()).changeReturnType(void.class);
+ *         this.setter = MethodHandles.publicLookup().bind(this, set, setType);
+ *       }
+ *     }
+ *     // class Main { public static void main(String... av) { ...
+ *     final Number[] stuff = { 123, 456 };
+ *     AssignableMethodHandle stuffPtr = new AssignableMethodHandle("get", "set") {
+ *         public Number get(long i)           { return stuff[(int)i]; }
+ *         public void   set(long i, Object x) {        stuff[(int)i] = x; }
+ *     }
+ *     int x = (Integer) stuffPtr.&lt;Number&gt;invokeExact(1L);  // 456
+ *     stuffPtr.setter().&lt;void&gt;invokeExact(0L, (Number) 789);  // replaces 123 with 789
+ * </pre></blockquote>
