AW: Third party library locations

Just for your info: Eclipse has an extra classloader for each plugin.

I'm not 100% sure about this ... but isn't there a way to configure (or
write) a class loader so that you can isolate classes?

I seem to recall that Eclipse's plug-in mechanism has some ability to
keep jar's that are included in one plug-in from conflicting with the
jar's of another plug-in.

And this is exactly where my heads begins to throb and my eye bulge.
From a purely common sense point of view, I find it difficult to think
that a single JVM can have two classes with the same package and
signature. Can't be done, I don't think (how would you know which was
which?). So the trick is to have multiple JVMs, but obviously those two
JVMs can't then share objects between them (unless they use some sort of
RMI technique).

Class versioning makes me a little bit crazy...
