> There are two potential NPEs in util.introspection.MethodKey (discovered by Eclipse)
> isInvocationConvertible
> isStrictInvocationConvertible
> Both methods check for actual == null, but the check is part of a compound and condition so actual may still be null.
> The comments suggest that actual should not be null, so the code should either drop the null check entirely or check it properly.
