27 | * Shared source for 'java' command line tool. |
28 | * |
29 | * If JAVA_ARGS is defined, then acts as a launcher for applications. For |
30 | * instance, the JDK command line tools such as javac and javadoc (see |
31 | * makefiles for more details) are built with this program. Any arguments |
32 | * prefixed with '-J' will be passed directly to the 'java' command. |
33 | */ |
34 | |
35 | /* |
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. |

1946 | * Read the jvm.cfg file and fill the knownJVMs[] array. |
1947 | * |
1948 | * The functionality of the jvm.cfg file is subject to change without |
1949 | * notice and the mechanism will be removed in the future. |
1950 | * |
1951 | * The lexical structure of the jvm.cfg file is as follows: |
1952 | * |
1953 | * jvmcfg := { vmLine } |
1954 | * vmLine := knownLine |
1955 | * | aliasLine |
1956 | * | warnLine |
1957 | * | ignoreLine |
1958 | * | errorLine |
1959 | * | predicateLine |
1960 | * | commentLine |
1961 | * knownLine := flag "KNOWN" EOL |
1962 | * warnLine := flag "WARN" EOL |
1963 | * ignoreLine := flag "IGNORE" EOL |
1964 | * errorLine := flag "ERROR" EOL |
1965 | * aliasLine := flag "ALIASED_TO" flag EOL |
1966 | * predicateLine := flag "IF_SERVER_CLASS" flag EOL |
1967 | * commentLine := "#" text EOL |
1968 | * flag := "-" identifier |
1969 | * |
1970 | * The semantics are that when someone specifies a flag on the command line: |
1971 | * - if the flag appears on a knownLine, then the identifier is used as |
1972 | * the name of the directory holding the JVM library (the name of the JVM). |
1973 | * - if the flag appears as the first flag on an aliasLine, the identifier |
1974 | * of the second flag is used as the name of the JVM. |
1975 | * - if the flag appears on a warnLine, the identifier is used as the |
1976 | * name of the JVM, but a warning is generated. |
1977 | * - if the flag appears on an ignoreLine, the identifier is recognized as the |
1978 | * name of a JVM, but the identifier is ignored and the default vm used |
1979 | * - if the flag appears on an errorLine, an error is generated. |
1980 | * - if the flag appears as the first flag on a predicateLine, and |
1981 | * the machine on which you are running passes the predicate indicated, |
1982 | * then the identifier of the second flag is used as the name of the JVM, |
1983 | * otherwise the identifier of the first flag is used as the name of the JVM. |
1984 | * If no flag is given on the command line, the first vmLine of the jvm.cfg |
1985 | * file determines the name of the JVM. |
1986 | * PredicateLines are only interpreted on first vmLine of a jvm.cfg file, |
1987 | * since they only make sense if someone hasn't specified the name of the |
1988 | * JVM on the command line. |
1989 | * |
1990 | * The intent of the jvm.cfg file is to allow several JVM libraries to |
1991 | * be installed in different subdirectories of a single JRE installation, |
1992 | * for space-savings and convenience in testing. |
1993 | * The intent is explicitly not to provide a full aliasing or predicate |
1994 | * mechanism. |
