Comment 1 Philipe Mulet

Reproduced. Problem did occur if getMethod(selector) was invoked, and 
attempted to resolve a method which signature had problems. Indeed, it 
nullified the method decl binding slot, and redid entire method resolution, 
and reentered same code (this time unable to find proper decl for binding).
Added protection to resolution of a method so as to return null in case unable 
to find method decl.

Added regression test ReconcilerTests.testMethodWithError14()
