I like your code changes and your tests.
One small comment:
1. verifier.cpp around line 2849 - could you possibly fix the comment - it says
"Class file parser verifies that methods with '<' have void return"
-- we only check <init> now which is what that logic cares about

But, the JVM Spec 8 says that such <clinit> methods should be ignored. See http://docs.oracle.com/javase/specs/jvms/se8/html/jvms-2.html#jvms-2.9 for details.
