/*
|
|
* 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.

|
|
* 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.
