to debug on linux you should export LD_LIBRARY_PATH for GDB:

export LD_LIBRARY_PATH=$jre/bin:$jre/bin/default

soft links inside, surprize, surprize:)

There is a useful trick discovered by Ivan Volosyuk. To get the correct LD_LIBRARY_PATH which wouldn't trigger process re-execing in the launcher (this breaks gdb and you won't be able to debug VM) just run some java program which doesn't finish immediately. Then take a look at /proc/`pidof java`/environ and copy LD_LIBRARY_PATH setting from it. This is the exact string which launcher uses when it re-exacs the process. If you copy it exactly to LD_LIBRARY_PATH setting launcher won't do exec.

Last time I checked one of directories had to have '/' in the end. So when things like this change it is safer to use this trick and use the string which current launcher wants.
