Thanks Jon.

Here are three suspected issues boiled down to simple test cases. Right now
they are all failing with the 1.8.0_60 javac. I'm not up-to-date enough on
current compiler development to know whether these are already fixed in
jdk9 or not.

Lambda generates IllegalAccessError at runtime:

Compilation failure when overriding clone()

Compilation fails when assigning static final field using qualified name
