duke@435 | 57 | * One job of the launcher is to remove command line options which the |
duke@435 | 58 | * vm does not understand and will not process. These options include |
duke@435 | 59 | * options which select which style of vm is run (e.g. -client and |
duke@435 | 60 | * -server) as well as options which select the data model to use. |
duke@435 | 61 | * Additionally, for tools which invoke an underlying vm "-J-foo" |
duke@435 | 62 | * options are turned into "-foo" options to the vm. This option |
duke@435 | 63 | * filtering is handled in a number of places in the launcher, some of |
duke@435 | 64 | * it in machine-dependent code. In this file, the function |
duke@435 | 65 | * CheckJVMType removes vm style options and TranslateDashJArgs |
duke@435 | 66 | * removes "-J" prefixes. On unix platforms, the |
duke@435 | 67 | * CreateExecutionEnvironment function from the unix java_md.c file |
duke@435 | 68 | * processes and removes -d<n> options. However, in case |
duke@435 | 69 | * CreateExecutionEnvironment does not need to exec because |
duke@435 | 70 | * LD_LIBRARY_PATH is set acceptably and the data model does not need |
duke@435 | 71 | * to be changed, ParseArguments will screen out the redundant -d<n> |
duke@435 | 72 | * options and prevent them from being passed to the vm; this is done |

duke@435 | 96 | * options which specify the version are not passed to the exec'd version, |

duke@435 | 382 | * Get the application's main class. |
duke@435 | 383 | * |
duke@435 | 384 | * See bugid 5030265. The Main-Class name has already been parsed |
duke@435 | 385 | * from the manifest, but not parsed properly for UTF-8 support. |
duke@435 | 386 | * Hence the code here ignores the value previously extracted and |
duke@435 | 387 | * uses the pre-existing code to reextract the value. This is |
duke@435 | 388 | * possibly an end of release cycle expedient. However, it has |
duke@435 | 389 | * also been discovered that passing some character sets through |
duke@435 | 390 | * the environment has "strange" behavior on some variants of |
duke@435 | 391 | * Windows. Hence, maybe the manifest parsing code local to the |
duke@435 | 392 | * launcher should never be enhanced. |
duke@435 | 393 | * |
duke@435 | 394 | * Hence, future work should either: |
duke@435 | 395 | * 1) Correct the local parsing code and verify that the |
duke@435 | 396 | * Main-Class attribute gets properly passed through |
duke@435 | 397 | * all environments, |
duke@435 | 398 | * 2) Remove the vestages of maintaining main_class through |
duke@435 | 399 | * the environment (and remove these comments). |

duke@435 | 1606 | * |
duke@435 | 1607 | * The lexical structure of the jvm.cfg file is as follows: |

duke@435 | 1621 | * aliasLine := flag "ALIASED_TO" flag EOL |
duke@435 | 1622 | * predicateLine := flag "IF_SERVER_CLASS" flag EOL |
duke@435 | 1623 | * commentLine := "#" text EOL |
duke@435 | 1624 | * flag := "-" identifier |
duke@435 | 1625 | * |
duke@435 | 1626 | * The semantics are that when someone specifies a flag on the command line: |
duke@435 | 1627 | * - if the flag appears on a knownLine, then the identifier is used as |
duke@435 | 1628 | * the name of the directory holding the JVM library (the name of the JVM). |
duke@435 | 1629 | * - if the flag appears as the first flag on an aliasLine, the identifier |
duke@435 | 1630 | * of the second flag is used as the name of the JVM. |
duke@435 | 1631 | * - if the flag appears on a warnLine, the identifier is used as the |
duke@435 | 1632 | * name of the JVM, but a warning is generated. |
duke@435 | 1633 | * - if the flag appears on an ignoreLine, the identifier is recognized as the |
duke@435 | 1634 | * name of a JVM, but the identifier is ignored and the default vm used |
duke@435 | 1635 | * - if the flag appears on an errorLine, an error is generated. |
duke@435 | 1636 | * - if the flag appears as the first flag on a predicateLine, and |
duke@435 | 1637 | * the machine on which you are running passes the predicate indicated, |
duke@435 | 1638 | * then the identifier of the second flag is used as the name of the JVM, |
duke@435 | 1639 | * otherwise the identifier of the first flag is used as the name of the JVM. |
duke@435 | 1640 | * If no flag is given on the command line, the first vmLine of the jvm.cfg |
duke@435 | 1641 | * file determines the name of the JVM. |
duke@435 | 1642 | * PredicateLines are only interpreted on first vmLine of a jvm.cfg file, |
duke@435 | 1643 | * since they only make sense if someone hasn't specified the name of the |
duke@435 | 1644 | * JVM on the command line. |
duke@435 | 1645 | * |
duke@435 | 1646 | * The intent of the jvm.cfg file is to allow several JVM libraries to |
duke@435 | 1647 | * be installed in different subdirectories of a single JRE installation, |
duke@435 | 1648 | * for space-savings and convenience in testing. |
duke@435 | 1649 | * The intent is explicitly not to provide a full aliasing or predicate |
