Runtime.addShutdownHook() is the key (JRE 1.3+). Shutdown hooks are 
always executed by the VM, no matter how it exits. The only drawback is 
an extra permission when the app is forked:

permission java.lang.RuntimePermission "shutdownHooks";

According to the discussions at the JDC it is never guaranteed that the 
VM executes finalize(), whereas it is for shutdown hooks - I confirm 
this by my own practice.

Kind regards,
Bas
