[issue #1615] fixes a bug where equals and hashcode would mess up if both the outer and the inner class have generics, the inner is non-static, and you generate equals/hashcode on the inner.

Note that in general this is just broken; do not put non-static inner classes in generics-carrying classes in the first place!
