org.xwiki.security.authorization.cache.ConflictingInsertionException

All Implemented Interfaces:

Serializable

public class ConflictingInsertionException
extends Exception

This exception is thrown if two or more parallel threads have attempted to load the cache with the same entry at the same time as a right was updated, so the resulting entries are different. When this happens, there must be a pending event waiting to be delivered, which will remove the offending entry from the cache. Thus, the appropriate action is to restart the attempt to load the cache when catching this, after the lock that blocks the event delivery has ben released and required.
