58 * vm does not understand and will not process. These options include
|
|
|
59 * options which select which style of vm is run (e.g. -client and

|
60 * -server) as well as options which select the data model to use.
|

61 * Additionally, for tools which invoke an underlying vm "-J-foo"
|

62 * options are turned into "-foo" options to the vm. This option
|

|

66 * removes "-J" prefixes. On unix platforms, the
|
|
|
67 * CreateExecutionEnvironment function from the unix java_md.c file
|
|

68 * processes and removes -d<n> options. However, in case
|

69 * CreateExecutionEnvironment does not need to exec because
|
|

70 * LD_LIBRARY_PATH is set acceptably and the data model does not need

395 * 1) Correct the local parsing code and verify that the

|

|
|
|
1625 *
|
|
|
1626 * The semantics are that when someone specifies a flag on the command line:
|
|
|
1627 * - if the flag appears on a knownLine, then the identifier is used as
|
|
|
1628 * the name of the directory holding the JVM library (the name of the JVM).
|
|
|
1629 * - if the flag appears as the first flag on an aliasLine, the identifier
|
|
|
1630 * of the second flag is used as the name of the JVM.
|
|
|
1631 * - if the flag appears on a warnLine, the identifier is used as the
|
|
|
1632 * name of the JVM, but a warning is generated.
|
|
|
1633 * - if the flag appears on an ignoreLine, the identifier is recognized as the
|
|
|
1634 * name of a JVM, but the identifier is ignored and the default vm used
|
|
|
1635 * - if the flag appears on an errorLine, an error is generated.
|
|
|
1636 * - if the flag appears as the first flag on a predicateLine, and
|
|
|
1637 * the machine on which you are running passes the predicate indicated,
|
|
|
1638 * then the identifier of the second flag is used as the name of the JVM,
|
|
|
1639 * otherwise the identifier of the first flag is used as the name of the JVM.
|
|
|
1640 * If no flag is given on the command line, the first vmLine of the jvm.cfg
|
|
|
1641 * file determines the name of the JVM.
|
|
|
1642 * PredicateLines are only interpreted on first vmLine of a jvm.cfg file,
|
|
|
1643 * since they only make sense if someone hasn't specified the name of the
|
|
|
1644 * JVM on the command line.
|
|
|
1645 *
|
|
|
1646 * The intent of the jvm.cfg file is to allow several JVM libraries to
|
|
|
1647 * be installed in different subdirectories of a single JRE installation,
|
|
|
1648 * for space-savings and convenience in testing.
