Issue600790

When subclassing a java.util.List in Jython
and I want to override __setitem__ to accept either
a symbolic name or an integer index. However, when
I define the __setitem__ method in my Jython subtype, I 
get a "TypeError: only integer keys accepted"
exception.  It seems that since __setitem__ was defined
*automatically* for the List, my overriding method is 
never being called...

--------

 from java.lang import String
 from java.util import ArrayList
 
 class GoofyListMapThing (ArrayList):
 
     def __init__(self):
         self._elements = {}

     def __setitem__(self, key, element):
         print "GoofyListMapThing::__setitem__"
         # Handle string key or int key here...
 
     def __getitem__(self, key):
         print "GoofyListMapThing::__getitem__"
         # Handle string key or int key here...
 
 glmt = GoofyListMapThing()
 glmt["my-key"] = String("Element-1")    # fails!
 

This problem is caused by PyInstance always checking if it has a CollectionProxy(non-collection subclasses appear not to be affected).  If so it executes the CollectionProxies __setitem__(there are others, look for usage of getCollection() in PyInstance).  A possible patch is to check the various dictionaries before checking for a collection proxy and executing the returned function if there is one.

__findattr__ appears not to work, so the individual dictionaries may have to queried.

Added test to test_list_jy.py.  This is fixed, probably was fixed by
Charlie Groves when the java-newstyle-type branch was merged.
