* PROBLEM DESCRIPTION: Customers cannot override the default   *
*                      isolation level by creating a custom    *
*                      DataStoreHelper because the             *
*                      getIsolationLevel() method is marked    *

* RECOMMENDATION:                                              *
****************************************************************
Five of our DataStoreHelper classes mark the getIsolationLevel
method as final, and therefore customers cannot override this
method using a custom DataStoreHelper.  In addition, the mapping
of external DataStoreHelpers to InternalDataStoreHelpers is
broken such that the InternalGenericDataStoreHelper is always
returned when using a custom DataStoreHelper.
Problem conclusion
WebSphere Distributed defects 
PQ79783 and 183634 already address
these problems, so these changes have been merged in.  The final
declaration on the getIsolationLevel methods has been removed,
and logic has been added to return the InternalDataStoreHelper
based on meta data as opposed to the class name.
