You do not need bytecode editing for so simple case, a lot of security handling is implemented in the good old java.

System.setSecurityManager(SecurityManager) throw some Error (like ThreadDeath) in checkExit() and assuming System.exit(int) [erm Runtime.getRuntime().exit(int)] is invoked in the same thread, it should do it.
