Crash on linux: com.comsol.nativejni.geom.Geom3.createGeom3(Lcom/comsol/nativejni/CPointer;I)V

I have a java application which can run in standalone mode as well. When running on Windows (either from the Desktop GUI or in standalone mode), or on Linux (from the Desktop GUI), it runs without problems. When I try to run it on linux in standalone mode, it crashes with the following error message:
FATAL ERROR OCCURED: com.comsol.nativejni.geom.Geom3.createGeom3(Lcom/comsol/nativejni/CPointer;I)V
Fatal error occured: com.comsol.nativejni.geom.Geom3.createGeom3(Lcom/comsol/nativejni/CPointer;I)V
It happens both in versions 4.3b and 4.4
I am trying to figure out the problem, but in case anybody can give a quick hint what to look after, that would be a great help.
Thank you very much
Daniel
[edit]
Sorry, the 'Fatal error occured' text is produced my code. An exception is thrown somewhere in COMSOL, with the message 'com.comsol.nativejni.geom.Geom3.createGeom3(Lcom/comsol/nativejni/CPointer;I)V'

Instead of running the .class file from java, use the comsol executable in batch mode (it does some extra things compared to simply running your .class file from java directly, which seems to be needed), and pass the cmd line args through a temporary file:
1) I have a wrapper bash script, which writes the cmd line args into a file, and sets the environment variable COMSOL_CMD_LINE_ARGS_FILE to the full path of that file, and then runs
COMSOL_INSTALL_DIR/bin/comsol batch -inputfile MyClass.class
2) MyClass.class checks if the env variable COMSOL_CMD_LINE_ARGS_FILE is set. If yes, it reads the cmd line args from the file and parses them.
