Description

When the delegate has inherited protected methods, the code gets generated more than once for them, resulting in a compilation error.

def proxy = ProxyGenerator.instantiateDelegate([], [1, 2, 3])
==>
groovy.lang.GroovyRuntimeException: Error creating proxy: startup failed, Script1.groovy: 109: Repetitive method name/signature for method 'void removeRange(int, int)' in class 'ArrayList_delegateProxy'.
 @ line 109, column 10.Script1.groovy: 113: Repetitive method name/signature for method 'void removeRange(int, int)' in class 'ArrayList_delegateProxy'.
 @ line 113, column 10.
2 errors

The trouble is in getInheritedMethods which makes a list of all of the protected methods, but it adds entries for overridden protected methods in the superclasses.
