Thanks for all of you enlightening me :)

I am not a classloader expert, so I did not know of that separation 
possibility. But I just thought about the fact, that all loaded classes 
are available inside jedit to all other plugins. So I simply reasoned 
that there can only be one version of a class in memory.

Can you differ between private and public classes of a classloader? If 
you can't, it would not be possible to implement the suggested feature 
for having different versions of some utility jar for different plugins 
without breaking the plugin inter-operability, wouldn't it?
