The hybrid cache manager "hijacks" both ehcache and hazelcast mechanisms, and will fool those other cache managers into returning caches of those types even though they're not really "managed" by those managers. This algorithm takes account of that by giving caches returned by the hybrid manager priority, and ignoring caches of the same name returned from the other cache managers.
