* 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. On unix platforms, the
|
|
46 |
* CreateExecutionEnvironment function from the unix java_md.c file
|
|
47 |
* processes and removes -d<n> options. However, in case
|
|
48 |
* CreateExecutionEnvironment does not need to exec because
|
|
49 |
* LD_LIBRARY_PATH is set acceptably and the data model does not need
|

50 |
* to be changed, ParseArguments will screen out the redundant -d<n>
|

* See bugid 5030265. The Main-Class name has already been parsed
|

383 |
* from the manifest, but not parsed properly for UTF-8 support.
|
|
384 |
* Hence the code here ignores the value previously extracted and
|
|
385 |
* uses the pre-existing code to reextract the value. This is
|
|
386 |
* possibly an end of release cycle expedient. However, it has
|
|
387 |
* also been discovered that passing some character sets through
|
|
388 |
* the environment has "strange" behavior on some variants of
|
|
389 |
* Windows. Hence, maybe the manifest parsing code local to the
|
|
390 |
* launcher should never be enhanced.
|
|
391 |
*
|
|
392 |
* Hence, future work should either:
|
|
393 |
* 1) Correct the local parsing code and verify that the
|
|
394 |
* Main-Class attribute gets properly passed through
|
|
395 |
* all environments,
|
|
396 |
* 2) Remove the vestages of maintaining main_class through
|
|
397 |
* the environment (and remove these comments).

*
|

|
|
1642 |
* flag := "-" identifier
|
|
1643 |
*
|
|
1644 |
* The semantics are that when someone specifies a flag on the command line:
|
|
1645 |
* - if the flag appears on a knownLine, then the identifier is used as
|
|
1646 |
* the name of the directory holding the JVM library (the name of the JVM).
|
|
1647 |
* - if the flag appears as the first flag on an aliasLine, the identifier
|
|
1648 |
* of the second flag is used as the name of the JVM.
|
|
1649 |
* - if the flag appears on a warnLine, the identifier is used as the
|
|
1650 |
* name of the JVM, but a warning is generated.
|
|
1651 |
* - if the flag appears on an ignoreLine, the identifier is recognized as the
|
|
1652 |
* name of a JVM, but the identifier is ignored and the default vm used
|
|
1653 |
* - if the flag appears on an errorLine, an error is generated.
|
|
1654 |
* - if the flag appears as the first flag on a predicateLine, and
|
|
1655 |
* the machine on which you are running passes the predicate indicated,
|
|
1656 |
* then the identifier of the second flag is used as the name of the JVM,
|
|
1657 |
* otherwise the identifier of the first flag is used as the name of the JVM.
|
|
1658 |
* If no flag is given on the command line, the first vmLine of the jvm.cfg
|
|
1659 |
* file determines the name of the JVM.
|
|
1660 |
* PredicateLines are only interpreted on first vmLine of a jvm.cfg file,
|
|
1661 |
* since they only make sense if someone hasn't specified the name of the
|
|
1662 |
* JVM on the command line.
|
|
1663 |
*
|
|
1664 |
* The intent of the jvm.cfg file is to allow several JVM libraries to
|
|
1665 |
* be installed in different subdirectories of a single JRE installation,
|
|
1666 |
* for space-savings and convenience in testing.
|
|
1667 |
* The intent is explicitly not to provide a full aliasing or predicate
