Alexei Fedotov commented on HARMONY-2710:
-----------------------------------------

What happens?

1. compile_me() is invoked for A.<init>
2. This leads to class A initialization
3. This leads to class B initialization
4. This leads to runtime exception during class B initialization on step 8
5. This is converted to another exception on the step 10
