/* Eclipse Program Launcher
*
* This file forms the base of the eclipse_*.dll/so. This dll is loaded by eclipse.exe
* to start a Java VM, or alternatively it is loaded from Java to show the splash
* screen or write to the shared memory. See eclipseJNI.c for descriptions of the methods
* exposed to the Java program using JNI.
*
* To display a splash screen before starting the java vm, the launcher should be started
* with the location of the splash bitmap to use:
* -showsplash <path/to/splash.bmp>
* Otherwise, when the Java program starts, it should determine the location of
* the splash bitmap to be used and use the JNI method show_splash.
*
* When the Java program initialization is complete, the splash window
* is brought down by calling the JNI method takedown_splash.
*
* The Java program can also call the get_splash_handle method to get the handle to the splash
* window. This can be passed to SWT to create SWT widgets in the splash screen.
*
* The Java application will receive two other arguments:
* -exitdata <shared memory id>
*
* The java program can call set_exit_data with this shared-memory-id
* to provide specific exit data to the launcher.
*
* The exit data size must not exceed MAX_SHARED_LENGTH which is
* 16Kb. The interpretation of the exit data is dependent on the
* exit value of the java application.
*
* The main launcher recognizes the following exit codes from the
* Java application:
*
* 0 - Exit normally.
* RESTART_LAST_EC = 23
* - restart the java VM again with the same arguments as the previous one.
* RESTART_NEW_EC = 24
* - restart the java VM again with the arguments taken from the exit data.
* The exit data format is a list of arguments separated by '\n'. The Java
* application should build this list using the arguments passed to it on
* startup. See below.
*
* Additionally, if the Java application exits with an exit code other than the
* ones above, the main launcher will display an error message with the contents
* of the exit data. If the exit data is empty, a generic error message is
* displayed. The generic error message shows the exit code and the arguments
* passed to the Java application.
*
* The options that can be specified by the user to the launcher are:
* -vm <javaVM> the Java VM to be used
* -os <opSys> the operating system being run on
* -arch <osArch> the hardware architecture of the OS: x86, sparc, hp9000
* -ws <gui> the window system to be used: win32, gtk, cocoa, ...
* -nosplash do not display the splash screen. The java application will
* not receive the -showsplash command.
* -showsplash <bitmap> show the given bitmap in the splash screen.
* -name <name> application name displayed in error message dialogs and
* splash screen window. Default value is computed from the
* name of the executable - with the first letter capitalized
* if possible. e.g. eclipse.exe defaults to the name Eclipse.
* -startup <startup.jar> the startup jar to execute. The argument is first assumed to be
* relative to the path of the launcher. If such a file does not
* exist, the argument is then treated as an absolute path.
* The default is find the plugins/org.eclipse.equinox.launcher jar
* with the highest version number.
* The jar must contain an org.eclipse.equinox.launcher.Main class.
* (unless JNI invocation is not being used, then the jar only needs to be
* an executable jar)
* -library the location of the eclipse launcher shared library (this library) to use
* By default, the launcher exe (see eclipseMain.c) finds
* <userArgs> arguments that are passed along to the Java application
* (i.e, -data <path>, -debug, -console, -consoleLog, etc)
* -vmargs <userVMargs> ... a list of arguments for the VM itself
*
* The -vmargs option and all user specified VM arguments must appear
* at the end of the command line, after all arguments that are
* being passed to Java application.
*
* The argument order for the new Java VM process is as follows:
*
* <javaVM> <all VM args>
* -os <user or default OS value>
* -ws <user or default WS value>
* -arch <user or default ARCH value>
* -launcher <absolute launcher name>
* -name <application name>
* -library <eclipse library location>
* -startup <startup.jar location>
* [-showsplash]
* [-exitdata <shared memory id>]
* <userArgs>
* -vm <javaVM>
* -vmargs <all VM args>
*
* where:
* <all VM args> =
* [<defaultVMargs | <userVMargs>]
* -jar
* <startup jar full path>
*
* The startup jar must be an executable jar.
*
*
* See "Main.java" for a simple implementation of the Java
* application.
*
* Configuration file
* The launcher gets arguments from the command line and/or from a configuration file.
* The configuration file must have the same name and location as the launcher executable
* and the extension .ini. For example, the eclipse.ini configuration file must be
* in the same folder as the eclipse.exe or eclipse executable (except in the case of
* Mac OS X where the eclipse.ini can be read from a Mac specific configuration folder
* recommended by the OS, see bugs 461725 and 461728 for more details).
*
* The format of the ini file matches that of the command line arguments - one
* argument per line.
* In general, the settings of the config file are expected to be overriden by the
* command line.
* - launcher arguments (-os, -arch...) set in the config file are overriden by the command line
* - the -vmargs from the command line replaces in its entirety the -vmargs from the config file.
* - user arguments from the config file are prepended to the user arguments defined in the
* config file. This is consistent with the java behaviour in the following case:
* java -Dtest="one" -Dtest="two" ... : test is set to the value "two"
