36 * One job of the launcher is to remove command line options which the
37 * vm does not understand and will not process. These options include
38 * options which select which style of vm is run (e.g. -client and
39 * -server) as well as options which select the data model to use.
40 * Additionally, for tools which invoke an underlying vm "-J-foo"
41 * options are turned into "-foo" options to the vm. This option
42 * filtering is handled in a number of places in the launcher, some of
43 * it in machine-dependent code. In this file, the function
44 * CheckJvmType removes vm style options and TranslateApplicationArgs
45 * removes "-J" prefixes. The CreateExecutionEnvironment function processes
46 * and removes -d<n> options. On unix, there is a possibility that the running
47 * data model may not match to the desired data model, in this case an exec is
48 * required to start the desired model. If the data models match, then
49 * ParseArguments will remove the -d<n> flags. If the data models do not match
50 * the CreateExecutionEnviroment will remove the -d<n> flags.

1570 * | aliasLine
1571 * | warnLine
1572 * | ignoreLine

1574 * | predicateLine
1575 * | commentLine

1577 * warnLine := flag "WARN" EOL
1578 * ignoreLine := flag "IGNORE" EOL
1579 * errorLine := flag "ERROR" EOL
1580 * aliasLine := flag "ALIASED_TO" flag EOL
1581 * predicateLine := flag "IF_SERVER_CLASS" flag EOL
1582 * commentLine := "#" text EOL
1583 * flag := "-" identifier
1584 *
1585 * The semantics are that when someone specifies a flag on the command line:
1586 * - if the flag appears on a knownLine, then the identifier is used as
1587 * the name of the directory holding the JVM library (the name of the JVM).
1588 * - if the flag appears as the first flag on an aliasLine, the identifier
1589 * of the second flag is used as the name of the JVM.
1590 * - if the flag appears on a warnLine, the identifier is used as the
1591 * name of the JVM, but a warning is generated.
1592 * - if the flag appears on an ignoreLine, the identifier is recognized as the
1593 * name of a JVM, but the identifier is ignored and the default vm used
1594 * - if the flag appears on an errorLine, an error is generated.
1595 * - if the flag appears as the first flag on a predicateLine, and
1596 * the machine on which you are running passes the predicate indicated,
1597 * then the identifier of the second flag is used as the name of the JVM,
1598 * otherwise the identifier of the first flag is used as the name of the JVM.
1599 * If no flag is given on the command line, the first vmLine of the jvm.cfg
1600 * file determines the name of the JVM.
1601 * PredicateLines are only interpreted on first vmLine of a jvm.cfg file,
1602 * since they only make sense if someone hasn't specified the name of the
1603 * JVM on the command line.
1604 *
1605 * The intent of the jvm.cfg file is to allow several JVM libraries to
1606 * be installed in different subdirectories of a single JRE installation,
1607 * for space-savings and convenience in testing.
1608 * The intent is explicitly not to provide a full aliasing or predicate
1609 * mechanism.
