Good.

>>> JVMCI had it own custom version of the resolution logic when it should be doing something similar to what ciMethod::resolve_invoke is doing. This required a semantic change that if the type is an interface no meaningful answer can be provided. I updated tests and the interface a little to reflect this.

I rearranged the code a little for this to ensure that code wasn't executed for the Compiler thread. It passes the graal gate with these changes.  A modified version of the test which found the issue also passes now.  I filed a bug suggesting changes to that test that would make it work better with compiler like C2 and Graal that don’t handle unloaded classes.  https://bugs.openjdk.java.net/browse/JDK-8154904 <https://bugs.openjdk.java.net/browse/JDK-8154904>
