HashMap: some methods not implemented

=======================================================================

DEFECT ABSTRACT : HashMap: some methods not implemented
AFFECTED TEST CASES :

DRIVER : /X10/drivers/sles11/220/110624
Checked out revision 22318
========================================================================
PROBLEM DESCRIPTION
------------------------------------------------------------------------

Some of the methods of HashMap nested classes are not yet implemented and
just throw "UnsupportedOperationException"

HashMap.x10:277: public def add(k: Key): Boolean

{ throw new UnsupportedOperationException(); }
HashMap.x10:278: public def remove(k: Key): Boolean { throw new UnsupportedOperationException(); }

HashMap.x10:279: public def clone(): KeySet[Key,Value]

{ throw new UnsupportedOperationException(); }
HashMap.x10:295: public def contains(k: Map.Entry[Key,Value]): Boolean { throw new UnsupportedOperationException(); }

HashMap.x10:296: public def add(k: Map.Entry[Key,Value]): Boolean

{ throw new UnsupportedOperationException(); }
HashMap.x10:297: public def remove(k: Map.Entry[Key,Value]): Boolean { throw new UnsupportedOperationException(); }

HashMap.x10:298: public def clone(): EntrySet[Key,Value]

{ throw new UnsupportedOperationException(); }

This defect is to keep track on that implementation not to go unintentionally
for too long (since defects are re-reviewed with product releases)
