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

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
|
|
|
63 * filtering is handled in a number of places in the launcher, some of

64 * it in machine-dependent code. In this file, the function
|
|
|
65 * CheckJVMType removes vm style options and TranslateApplicationArgs
|

|
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
|
|

1813 * notice and the mechanism will be removed in the future.
|
|
|
1814 *
|

1817 * jvmcfg := { vmLine }
|

|

1826 * warnLine := flag "WARN" EOL
|
|
|
1827 * ignoreLine := flag "IGNORE" EOL
|
|
|
1828 * errorLine := flag "ERROR" EOL
|
|
|
1829 * aliasLine := flag "ALIASED_TO" flag EOL
|
|
|
1830 * predicateLine := flag "IF_SERVER_CLASS" flag EOL
|
|
|
1831 * commentLine := "#" text EOL
|
|
|
1832 * flag := "-" identifier
|
|
|
1833 *
|
|
|
1834 * The semantics are that when someone specifies a flag on the command line:
|
|
|
1835 * - if the flag appears on a knownLine, then the identifier is used as
|
|
|
1836 * the name of the directory holding the JVM library (the name of the JVM).
|
|
|
1837 * - if the flag appears as the first flag on an aliasLine, the identifier
|
|
|
1838 * of the second flag is used as the name of the JVM.
|
|
|
1839 * - if the flag appears on a warnLine, the identifier is used as the
|
|
|
1840 * name of the JVM, but a warning is generated.
|
|
|
1841 * - if the flag appears on an ignoreLine, the identifier is recognized as the
|
|
|
1842 * name of a JVM, but the identifier is ignored and the default vm used
|
|
|
1843 * - if the flag appears on an errorLine, an error is generated.
|
|
|
1844 * - if the flag appears as the first flag on a predicateLine, and
|
|
|
1845 * the machine on which you are running passes the predicate indicated,
|
|
|
1846 * then the identifier of the second flag is used as the name of the JVM,
|
|
|
1847 * otherwise the identifier of the first flag is used as the name of the JVM.
|
|
|
1848 * If no flag is given on the command line, the first vmLine of the jvm.cfg
|
|
|
1849 * file determines the name of the JVM.
|
|
|
1850 * PredicateLines are only interpreted on first vmLine of a jvm.cfg file,
|
|
|
1851 * since they only make sense if someone hasn't specified the name of the
|
|
|
1852 * JVM on the command line.
|
|
|
1853 *
|
|
|
1854 * The intent of the jvm.cfg file is to allow several JVM libraries to
|
|
|
1855 * be installed in different subdirectories of a single JRE installation,
|
|
|
1856 * for space-savings and convenience in testing.
|
|
|
1857 * The intent is explicitly not to provide a full aliasing or predicate
|
|
|
1858 * mechanism.
