> The testcase below demonstrates the problem. 
> The first invocation of CtNewMethod#make works, the second one fails.
> It looks like the problem is related with MemberResolver#lookupMethod.
> The check to enable the creation of a recursively called method is not precise enough. It actually succeeds, although the current method is an instance method, and the method which shall be invoked is a static method.
