[RESOLVED] Forcing a class to "die" ?

[MalcolmCarmen]

Here's the problem - I have a plugin loading mechanism that dynamically loads classes like this:

- Define a variable as the class
- put the variable in an arraylist

The problem now is that when I attempt to unload such a plugin using .remove() with the arraylist, the class instance is still there. I noticed this when one of the plugins (a basic HTTPd) was still listening on a port when it should have been unloaded.

I've already tried using
System.runFinalization();
System.gc();

Thanks for any help!
