Thilo Goetz commented on UIMA-607:
----------------------------------
I don't think so, but I'm not the expert. Each pear is supposed to be an
encapsulated component that doesn't see the datapath of its neighbors. We
certainly need the individual class loaders. If they're tied in with the
resource manager, then that's another reason we need a new resource manager for
each pear.
We may have to wait for Michael to come back from vacation...
