23 | * This exception is thrown if two or more parallel threads have attempted to load the cache with the same entry at the | |
24 | * same time as a right was updated, so the resulting entries are different. | |
25 | * | |
26 | * When this happens, there must be a pending event waiting to be delivered, which will remove the offending entry from | |
27 | * the cache. Thus, the appropriate action is to restart the attempt to load the cache when catching this, after the | |
28 | * lock that blocks the event delivery has ben released and required. | |
