Class.forName
, which accepts a null
ClassLoader
reference as well).

DefaultFoo.bar()
. This enables attributes on that method to be found.
NOTE: In contrast to AopUtils.getMostSpecificMethod(java.lang.reflect.Method, java.lang.Class<?>)
,
this method does not resolve Java 5 bridge methods automatically.
Call BridgeMethodResolver.findBridgedMethod(java.lang.reflect.Method)
if bridge method resolution is desirable (e.g. for obtaining metadata from
the original method definition).
NOTE: Since Spring 3.1.1, if Java security settings disallow reflective
access (e.g. calls to Class#getDeclaredMethods
etc, this implementation
will fall back to returning the originally provided method.

implementations of the GroovyObject

Note that, despite being synthetic, bridge methods (Method.isBridge()
) are considered
as user-level methods since they are eventually pointing to a user-declared generic method.
