*** Bug 80949 has been marked as a duplicate of this bug. *** Simpler test case. Create an AST and resolve the following cu:
public class X {
<T> void foo(NonExisting arg) {
}
}
Created attachment 16642 [details]
Proposed patch
Fix consists in nullifying the type variable bindings if there is a problem
with the argument, so that there is no backpointer to an invalid method
binding.
