      Description

      It looks like somehow when using CacheStore with JBoss JTA it is possible to get into an endless loop. On the server our app is deployed one cpu is pegged at 100% usage. A thread dump revealed that a thread is executing AsyncStore.addWork() and never leaves (thread dump shows line 330, _overflowLock.wait()).

      Our cache size is set to 200k.

      Here is from the thread dump:

      "aggregation-1-14" prio=10 tid=0x00007f0508d0e800 nid=0x46e0 in Object.wait() [0x00007f050c8eb000]
