             Summary: Hibernate/Infinispan 2nd Level Caches set to transaction-mode=NONE stop functioning after an explicit eviction
                 Key: AS7-6365
                 URL: https://issues.jboss.org/browse/AS7-6365
             Project: Application Server 7
          Issue Type: Feature Request
          Components: JPA / Hibernate
    Affects Versions: 7.1.3.Final (EAP)
            Reporter: Fredrik Lagerblad
            Assignee: Scott Marlow


The caches in the 'infinispan' subsystem configured with <transaction mode="NONE"/> get stuck in state= CLEARING when you perform a programmatic evict() on them to clear the caches. (Using e.g. em.getEntityManagerFactory().getCache().evictAll() )
    
The problem seem to lie within the class 'org.hibernate.cache.infinispan.impl.BaseRegion, where the 'checkValid' method fails to clear the cache (and set back the state to VALID). The reason it fails is due to that it calls:  cacheAdapter.withinTx() , which in turn tries to get the TransactionManager from the cache (which seems to be null for these non-transactional caches), and then NPEs on the tm.begin(); The NPE is caught and logs out "Could not invalidate region: null", and never set the state in VALID. So from thereon the caches are in an Invalid state and is not used anymore by Infinispan, thus leading to much performance.
