> I've noticed that the overload selection mechanism based on parameter types is not working
when some parameters are assignable, in the sense of Class.isAssignableFrom(...).
> Given those methods:
> {code:borderStyle=solid}
> String toString(String input)
> String toString(int input)
> {code}
> We can select both methods via bean:toString(String) or bean:toString(int)
> But given those methods:
> {code:borderStyle=solid}
> String toString(String input)
> String toString(Object input)
> {code}
> bean:toString(String) end in selecting toString(Object).
> Ideally, I would expect it to select toString(String). Otherwise, unwinding an AmbiguousCallException
may perhaps apply.
> Thoughts:
> I'm wondering whether ObjectHelper.isOverridingMethod(...) would be mixing overload vs
override.
> Will attach a test case.
