- * One job of the launcher is to remove command line options which the

- * -server) as well as options which select the data model to use.
- * Additionally, for tools which invoke an underlying vm "-J-foo"
- * options are turned into "-foo" options to the vm.  This option
- * filtering is handled in a number of places in the launcher, some of
- * it in machine-dependent code.  In this file, the function
- * CheckJVMType removes vm style options and TranslateDashJArgs
- * removes "-J" prefixes.  On unix platforms, the
- * CreateExecutionEnvironment function from the unix java_md.c file
- * processes and removes -d<n> options.  However, in case
- * CreateExecutionEnvironment does not need to exec because
- * LD_LIBRARY_PATH is set acceptably and the data model does not need
- * to be changed, ParseArguments will screen out the redundant -d<n>
- * options and prevent them from being passed to the vm; this is done
- * by using the machine-dependent call
- * RemovableMachineDependentOption.

- *                    |   ignoreLine
- *                    |   errorLine
- *                    |   predicateLine
- *                    |   commentLine
- *     knownLine      :=  flag  "KNOWN"                  EOL
- *     warnLine       :=  flag  "WARN"                   EOL
- *     ignoreLine     :=  flag  "IGNORE"                 EOL
- *     errorLine      :=  flag  "ERROR"                  EOL
- *     aliasLine      :=  flag  "ALIASED_TO"       flag  EOL
- *     predicateLine  :=  flag  "IF_SERVER_CLASS"  flag  EOL
- *     commentLine    :=  "#" text                       EOL
- *     flag           :=  "-" identifier
- *
- * The semantics are that when someone specifies a flag on the command line:
- * - if the flag appears on a knownLine, then the identifier is used as
- *   the name of the directory holding the JVM library (the name of the JVM).
- * - if the flag appears as the first flag on an aliasLine, the identifier
- *   of the second flag is used as the name of the JVM.
- * - if the flag appears on a warnLine, the identifier is used as the
- *   name of the JVM, but a warning is generated.
- * - if the flag appears on an ignoreLine, the identifier is recognized as the
- *   name of a JVM, but the identifier is ignored and the default vm used
- * - if the flag appears on an errorLine, an error is generated.
- * - if the flag appears as the first flag on a predicateLine, and
- *   the machine on which you are running passes the predicate indicated,
- *   then the identifier of the second flag is used as the name of the JVM,
- *   otherwise the identifier of the first flag is used as the name of the JVM.
- * If no flag is given on the command line, the first vmLine of the jvm.cfg
- * file determines the name of the JVM.
- * PredicateLines are only interpreted on first vmLine of a jvm.cfg file,
- * since they only make sense if someone hasn't specified the name of the
- * JVM on the command line.
- *
- * The intent of the jvm.cfg file is to allow several JVM libraries to
- * be installed in different subdirectories of a single JRE installation,
- * for space-savings and convenience in testing.
- * The intent is explicitly not to provide a full aliasing or predicate
- * mechanism.

- * Flowchart of launcher execs and options processing on unix

- *
- * The version specification (if any) is processed first by the
- * platform independent routine SelectVersion.  This may result in
- * the exec of the specified launcher version.
- *
- * Typically, the launcher execs at least once to ensure a suitable
- * LD_LIBRARY_PATH is in effect for the process.  The first exec
- * screens out all the data model options; leaving the choice of data
- * model implicit in the binary selected to run.  However, in case no
- * exec is done, the data model options are screened out before the vm
- * is invoked.

+ * Flowchart of launcher execs and options processing on unix

+ *
+ * The version specification (if any) is processed first by the
+ * platform independent routine SelectVersion.  This may result in
+ * the exec of the specified launcher version.
+ *
+ * Typically, the launcher execs at least once to ensure a suitable
+ * LD_LIBRARY_PATH is in effect for the process.  The first exec
+ * screens out all the data model options; leaving the choice of data
+ * model implicit in the binary selected to run.  However, in case no
+ * exec is done, the data model options are screened out before the vm
+ * is invoked.

- *        same directory where the launcher exists, so we don't have to
- *        worry about choosing the right JVM based on command line flag, jar
- *        file and/or ergonomics. Intead of removing unused logic from source
- *        they are commented out with #ifndef GAMMA, hopefully it'll be easier
- *        to maintain this file in sync with regular JDK launcher.

- * One job of the launcher is to remove command line options which the
- * vm does not understand and will not process.  These options include
- * options which select which style of vm is run (e.g. -client and
- * -server) as well as options which select the data model to use.
- * Additionally, for tools which invoke an underlying vm "-J-foo"
- * options are turned into "-foo" options to the vm.  This option
- * filtering is handled in a number of places in the launcher, some of
- * it in machine-dependent code.  In this file, the function
- * CheckJVMType removes vm style options and TranslateDashJArgs
- * removes "-J" prefixes.  On unix platforms, the
- * CreateExecutionEnvironment function from the unix java_md.c file
- * processes and removes -d<n> options.  However, in case
- * CreateExecutionEnvironment does not need to exec because
- * LD_LIBRARY_PATH is set acceptably and the data model does not need
- * to be changed, ParseArguments will screen out the redundant -d<n>
- * options and prevent them from being passed to the vm; this is done
- * by using the machine-dependent call
- * RemovableMachineDependentOption.

- * Read the jvm.cfg file and fill the knownJVMs[] array.
- *
- * The functionality of the jvm.cfg file is subject to change without
- * notice and the mechanism will be removed in the future.
- *

- *
- *     jvmcfg         :=  { vmLine }
- *     vmLine         :=  knownLine
- *                    |   aliasLine
- *                    |   warnLine
- *                    |   ignoreLine
- *                    |   errorLine
- *                    |   predicateLine
- *                    |   commentLine
- *     knownLine      :=  flag  "KNOWN"                  EOL
- *     warnLine       :=  flag  "WARN"                   EOL
- *     ignoreLine     :=  flag  "IGNORE"                 EOL
- *     errorLine      :=  flag  "ERROR"                  EOL
- *     aliasLine      :=  flag  "ALIASED_TO"       flag  EOL
- *     predicateLine  :=  flag  "IF_SERVER_CLASS"  flag  EOL
- *     commentLine    :=  "#" text                       EOL
- *     flag           :=  "-" identifier
- *
- * The semantics are that when someone specifies a flag on the command line:
- * - if the flag appears on a knownLine, then the identifier is used as
- *   the name of the directory holding the JVM library (the name of the JVM).
- * - if the flag appears as the first flag on an aliasLine, the identifier
- *   of the second flag is used as the name of the JVM.
- * - if the flag appears on a warnLine, the identifier is used as the
- *   name of the JVM, but a warning is generated.
- * - if the flag appears on an ignoreLine, the identifier is recognized as the
- *   name of a JVM, but the identifier is ignored and the default vm used
- * - if the flag appears on an errorLine, an error is generated.
- * - if the flag appears as the first flag on a predicateLine, and
- *   the machine on which you are running passes the predicate indicated,
- *   then the identifier of the second flag is used as the name of the JVM,
- *   otherwise the identifier of the first flag is used as the name of the JVM.
- * If no flag is given on the command line, the first vmLine of the jvm.cfg
- * file determines the name of the JVM.
- * PredicateLines are only interpreted on first vmLine of a jvm.cfg file,
- * since they only make sense if someone hasn't specified the name of the
- * JVM on the command line.
- *
- * The intent of the jvm.cfg file is to allow several JVM libraries to
- * be installed in different subdirectories of a single JRE installation,
- * for space-savings and convenience in testing.
- * The intent is explicitly not to provide a full aliasing or predicate
- * mechanism.

- * Flowchart of launcher execs and options processing on unix

- * -d64, as well as a version specification which may have come from

- * The vm selection options are not passed to the running
- * virtual machine; they must be screened out by the launcher.
- *
- * The version specification (if any) is processed first by the
- * platform independent routine SelectVersion.  This may result in
- * the exec of the specified launcher version.
- *
- * Typically, the launcher execs at least once to ensure a suitable
- * LD_LIBRARY_PATH is in effect for the process.  The first exec
- * screens out all the data model options; leaving the choice of data
- * model implicit in the binary selected to run.  However, in case no
- * exec is done, the data model options are screened out before the vm
- * is invoked.
