+Diagnostics Examples.
+
+The "examples/ directory contains a collection of examples of Java code, each of
+which is designed to illustrate one or more diagnostics that can be generated by
+the JDK Java compiler, javac. These examples are represented by files or
+directories of files, each of which is designed to illustrate a specific
+diagnostic. Sometimes it is unavoidable that creating one issue will lead to
+downstream issues: this is especially true for lex errors, where the error
+recovery is fragile at best. Each example declares the diagnostics that it is
+expected to generate -- this allows the examples to be verified and facilitates
+searching for examples for specific messages.
+
+Normally, tests for javac errors avoid checking the actual error messages that
+get generated. Older tests simply verify that one or more warnings or errors
+are generated; more recent tests verify that specific messages are generated,
+but these tests typically avoid checking the localized text by using the
+-XDrawDiagnostics mechanism. In addition, the focus of such tests is often on
+completeness instead of simplicity.
+
+By contrast, the intent of these examples is to provide simple and easy to
+understand examples of the situations in which a diagnostic can arise, and the
+messages that may be displayed. This will aid in reviewing the output generated
+by javac and in localizing the resource bundle to other locales. In addition,
+the examples include simple meta-information so that the collection as a whole
+can be audited for coverage, thus encouraging new examples to be added when new
+diagnostics are added to javac.
+
+There are two utilities for processing these examples.
+
+The first utility is "CheckExamples" which checks various conditions for the
+examples:
+-- each example must generate exactly the set of keys that it is declared to
+   generate
+-- together, the examples must generate all the resource keys coming from javac
+   (except for resource keys that are registered in a "not yet" list)
+-- the "not yet" list should only contain those resource keys from javac that
+   are not covered by any example
+
+CheckExamples can be run standalone, and as a jtreg test, and will fail if any
+anomalous conditions are found.
+
+The second utility is "RunExamples" which runs selected examples or all of them.
+The examples can be run with -XDrawDiagnostics or without.   Examples can be
+selected by name or by resource key.   Most examples are simple to run directly
+anyway, but some use annotation processors or sourcepath or other options, and
+the framework handles all these requirements.
+
+RunExamples can be run standalone and as a jtreg test, in which case it
+generates a simple plain text report. In addition, the langtools/make/build.xml
+file has a target "diags-examples" that uses RunExamples to create an HTML
+report containing the output from all the examples.
+
+
+Adding examples.
+
+When new diagnostics are added to javac, CheckExamples will probably initially
+fail because the diagnostic will not have a corresponding example, nor will the
+resource key be registered in the "not yet" list. Avoid the temptation to
+simply add the resource key to the "not yet" list, except as a last resort.
+
+Examples should be as simple as possible to illustrate a diagnostic.  An example
+that is a single file is to be preferred over multiple files. An example that
+generates just the one intended diagnostic is to be preferred over one that
+generates multiple diagnostics. Examples should be a simple illustration of the
+conditions that give rise to the diagnostic and should be easy to understand by
+the reviewer and, potentially, by the localization folk, who have to understand
+the context in which these new messages can appear.
+
+
+Specification for writing examples.
+
+An example may a single file or a directory of files directly in the "examples"
+directory. One file within an example must contain meta-information such as the
+keys that it generates, any javac options that may be required, and additional
+info about how to run the test, if needed.
+
+If an example is represented by a directory of files, by default all files
+within that directory will be compiled together, putting all the files on the
+command line. However, some subdirectories are special:
+-- processors/
+    Files within this directory will be treated as annotation processors and
+    compiled ahead of time. Currently, annotation processors are made available
+    to javac using the -classpath option (not -processorpath). This is to avoid
+    explicit use of annotation processing options on the javac command line.
+    Any annotation processors found will be registered for access by the JDK
+    service loaded. Currently, annotation processors are assumed to be in the
+    unnamed package.
+-- sourcepath/
+    If present, this directory will be put passed to javac using the -sourcepath
+    option.
+-- classpath/
+    This name is reserved for future use. It is expected that this directory
+    will be used to provide classes to be compiled and passes to javac via the
+    -classpath option.
+-- support/
+    This name is reserved for future use. It is expected that this directory
+    will be used to provide classes that setup non-standard conditions for a
+    test, such as very large source files, or illegal class files.
+
+Meta-information is represented by simple comment lines in exactly one of the
+source files of the example.  The file must not be in one of the special
+subdirectories (processors/, sourcepath/, classpath/ or support/). Three
+different types of information may be given:
+// key: <resource-key>
+    One or more such lines must be provided, declaring the full resource keys
+    that will be used by javac when this example is run.
+// options: <javac-options>
+    This line may be given at most once, providing one or more options to be
+    passed to javac. It is not possible to use this to specify options that
+    require filenames or directories.
+// run: <mode> <optional-args>
+    This line may be given at most once, providing infomation about how to
+    run the example. Three different kinds are supported:
+    jsr199 -- The example will be run using the JSR 199 Compiler API.
+              This is the default if the tag is omitted. Messages generated
+              by the "rich diagnostic formatter" can not be accessed in this
+              way.  However, this mode does provide additional options for
+              simulating errors in the filesystem. (See the options below.)
+    simple -- The example will be run using the simple com.sun.tools.javac.Main
+              API. This mode is most like the normal command line invocation.
+    backdoor -- The example will be run using an internal "backdoor" API, that
+              interposes access to the main compiler message bundle. This mode
+              is required to detect and track messages that bypass the normal
+              diagnostic mechanisms, such as output generated by the -verbose
+              option.
+
+The "jsr199" run mode accepts the following options:
+    -cantRead:pattern
+    -cantWrite:pattern
+In both cases, the pattern is a standard Java regular expression (See the
+javadoc for java.util.regex.Pattern for a complete specification.) Attempts to
+read or write from files matching the corresponding pattern will cause an
+IOException to occur within javac.

+ * Utility to run selected or all examples, writing results to

+ * Options:
+ *  -examples dir       directory of examples. Defaults to ${test.src}/examples
+ *  -raw                run examples with -XDrawDiagnostics
+ *  -showFiles          include text of source files in the output
+ *  -verbose            verbose output
+ *  -o file             write output to file: format will be HTML if
+ *                      file has .html extension; otherwise it will be plain text.
+ *                      default is to stdout
+ *  -title string       specify a title, only applies to HTML output
