All calls are delegated to the cache associated with the currentBroker. When the broker was closed (returned to pool) the cache was cleared.

I.e. remove all entries for classes and objects. lookup public Object lookup(Identity oid)(Code) Lookup object with Identity oid in objectTable. Returns null if no matching id is found remove public void remove(Identity oid)(Code) Removes an Object from the cache.
