RE: [aspectj-users] aspectJ and System.exit().

Thanks Holger,
Runtime.getRuntime.addShutdownHook(Thread hook);
runs very fine ( detects System.exit(), and Control-C on Windows OS)

I can close properly my gzip log files !

There are the regular shutdown hooks, which are sadly much less useful
than they first appear to be:

You can always advise your own code to run before System.exit at either
call or execution. "around" might even work as well because of the way
"finally" works, though I would not bet on "after" :-)
