--    DESCRIPTION
--      This removes java related objects from the data dictionary.
--      If remove_all is true, it removes all java objects and java
--      related tables and packages, including user objects.
--      If remove all is false, it removes only the java objects, such
--      as system classes, that are considered to be a fixed part of a
--      given Oracle release.  It does not remove user objects.
--
--    NOTES
--      This procedure is destructive.  After it runs, System classes 
--      must be reloaded either by initjvm or in a subsequent 
--      upgraded/downgrade phase before Java is again usable.
--
--      This procedure requires a significant amount of rollback
--      to execute.
