Description Michael Rennie CLA 2007-09-11 13:39:16 EDT 
The implementation of hashcode() in WorkingSet violates the implementation guideline from the Java spec. The hashcode of an item cannot change over its lifecycle, which happens for workingsets, as their hashcodes are augmented with the hashcode of the element array.

This is the direct cause of bug 184915, where the change in hashcode for a workingset cause the element map of the tree to hold disposed widgets.
