Thanks again! I forgot that one. The release now runs as well!

Actually, I'm pretty sure that wasn't it. In 2.x they played some weird
class loader tricks, that IKVM initially had problems with, but nowadays
IKVM has support for that as well (by emitting reflection based code
when non-existing classes are referenced).

Yep and much appreciated.

Some things I'm seeing:
- New Java Project => Eclipse dies (just disappears without any
messages)
- Opening Existing Java Project => Java Source Editor doesn't work
