47 This is the app launcher program for application packaging on Windows, Mac,
48 and Linux.
49
50 Basic approach:
51 - Launcher (jpackageapplauncher) is executable that loads
52 applauncher.dll/libapplauncher.dylib/libapplauncher.so
53 and calls start_launcher below.
54 - Reads app/package.cfg or Info.plist or app/<appname>.cfg for application
55 launch configuration (package.cfg is property file).
56 - Load JVM with requested JVM settings (bundled client JVM if availble,
57 server or installed JVM otherwise).
58 - Wait for JVM to exit and then exit from Main
59 - To debug application by passing command line argument.
60 - Application folder is added to the library path (so LoadLibrary()) works.
61
62 Limitations and future work:
63 - Running Java code in primordial thread may cause problems
64 (example: can not use custom stack size).
65 Solution used by java launcher is to create a new thread to invoke JVM.
66 See CR 6316197 for more information.
