      With empty caches.
      1. Node A reads v1 from some data store, then calls cache.putForExternalRead(k,v1). A doesn't own k.
      2. Node B then calls cache.put(k,v2). B is the owner of k.
      3. Node A's copy of k is never invalidated.

      With empty caches. 1. Node A reads v1 from some data store, then calls cache.putForExternalRead(k,v1). A doesn't own k. 2. Node B then calls cache.put(k,v2). B is the owner of k. 3. Node A's copy of k is never invalidated.

      With transactional distributed caches it happens that Cache.putForExternalRead(k,v) places an entry into L1 that never gets invalidated. It seems to happen when the the owner of k doesn't have the entry. In this case the non owner puts k into his cache without having the owner registering this. Usually the owner stores all requesters in L1ManagerImpl.addRequester and sends out invalidations to the requesters. What should happen is that the entry is replicated to the owner.
