Hi Łukasz, can i somehow help with this? Is it all about classloader black magic or a normal programer can make any progress with this subject.
I understand that JDK8 is much more than just lambdas, so maybe i would be able to help with this "lambdas only" problem. I would be happy if S2.3.x would be abble to load such action classes but would not be fully compatible with JDK8. But maybe this is all or nothing case?
