Class cast bug

[lucacampanella]

Hi!
I get a class cast exception, looking at the code the problem seems to be in CtTypeReferenceImpl line 811

// case 2: this is an actual type argument of a method/constructor reference
if (parent instanceof CtExecutableReference) {
	CtExecutable<?> exec = ((CtExecutableReference<?>) parent).getExecutableDeclaration();
	if (exec instanceof CtMethod || exec instanceof CtConstructor) {
		return findTypeParamDeclarationByPosition((CtFormalTypeDeclarer) exec, ((CtTypeReference) parent).getActualTypeArguments().indexOf(this));
	}
}

Here we're checking if the parent is a CtExecutableReference, but then casting it to a CtTypeReference.

Thanks
Luca
