For backwards compatibility reasons, in a scenario with overloaded non-abstract methods of the given name, only the no-arg variant of a method will be turned into a container-driven lookup method.

In case of a provided Method, only straight matches will be considered, usually demarcated by the @Lookup annotation.

Specified by:

whether this override matches the given method

equals
