* PROBLEM DESCRIPTION: Robust Handling by Invalidation         *
*                      Thread required for an exception        *
*                      thrown in the valueUnbound method.      *

* RECOMMENDATION:                                              *
****************************************************************
The Invalidation Thread in the database persistence case during
listener processing reads in the object from the database and
invokes the valueUnbound method. If the valueUnbound method
throws a RunTime Exception the Invalidation Thread was halting
that particular round of invalidation processing and would
resume processing only after the sleep interval.
Problem conclusion
This has been changed so that the session on which the Runtime
exception is not invalidated and the Invalidation Thread
continues with the invalidation processing for the other
sessions.
