Hi, I'm working on a temporary solution to resolve method usages until we change the AST.
While trying to test it, type resolution failed with an IllegalStateException on a very simple primary (object.toString()). Here's the full stack trace of the exception:
java.lang.IllegalStateException: None of the maximally specific methods are abstract.

The code samples that trigger the exception are here. I think it's notable that the first test throws the exception but the second doesn't, the only difference being that in the first case, the source is loaded using a class literal and in the second it's provided as a string. The methods used to parse and visit the source are taken from ClassTypeResolverTest.
