Its not guaranteed to work but does (Sun VM) unless you explicitly disable it with a command line option (DisableExplicitGC). (You need to check your VM's documentation or just do it and observe the results ;-) )
Attach visual WM and force a GC and you can see the results, we do it all the time for debugging purposes.
Obviously writing a program relying on this behaviour is different, there's no guarantee it'll do anything.
