* Shared source for 'java' command line tool.
*
* If JAVA_ARGS is defined, then acts as a launcher for applications. For
* instance, the JDK command line tools such as javac and javadoc (see
* makefiles for more details) are built with this program.  Any arguments
* prefixed with '-J' will be passed directly to the 'java' command.

35/*
* 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 TranslateApplicationArgs
* removes "-J" prefixes.  The CreateExecutionEnvironment function processes
* and removes -d<n> options. On unix, there is a possibility that the running
* data model may not match to the desired data model, in this case an exec is
* required to start the desired model. If the data models match, then
* ParseArguments will remove the -d<n> flags. If the data models do not match
* the CreateExecutionEnviroment will remove the -d<n> flags.

* Read the jvm.cfg file and fill the knownJVMs[] array.

*     vmLine         :=  knownLine
*                    |   aliasLine

*                    |   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.
