is it pretty bad to call:
java.lang.Proxy.newInstance(...) often? Does it create a new class each
and every time? Can't believe I forgot about this one...I'm a f'n idiot.

javadoc says that its supposed to cache it, but... who knows...
I recently had to increase the permgen space of my maven build and
thought this might be it.

It caches it in a weak map.

Hmmm. so the class itself could be garbage collected and pergen space
still wasted?

Not sure exactly what you mean here. The actual cache looks something like (or would look
like this if the code used generics):
WeakHashMap<ClassLoader, Map<List<String>, WeakReference<Class>>
loaderToCache;
As both the proxy class and the CL are held weakly, it should not stop anything being
GC'ed.
