Subject [jira] Commented: (DERBY-1539) As per the functional spec attached to DERBY-1330, a trigger should be dropped when a privilege required by the trigger is revoked.

    [ http://issues.apache.org/jira/browse/DERBY-1539?page=comments#action_12422643 ] 
            
Daniel John Debrunner commented on DERBY-1539:
----------------------------------------------

WIll a Permissions descriptor now change its hashCode during its lifetime? From the code it
looks like that's a possibility.
I think that is not typical behaviour for objects and will lead to bugs that are hard to track
down. Fro example changing the
hashCode() return while an object is in a cache or hashtable is not supported, the object
will become "lost" in the hash table.

> A trigger tracks its privileges requirements using Derby's Dependency Manager. If any
one of those required privileges are revoked, the trigger should be dropped automatically.

> I am just creating a new jira entry here so it is easier to track sub items of DERBY-1330.
Will link this Jira entry to DERBY-1330.
