             Summary: NonTxInvalidationInterceptor added twice to cache used for Hibernate 2LC
                 Key: ISPN-5854
                 URL: https://issues.jboss.org/browse/ISPN-5854
             Project: Infinispan
          Issue Type: Bug
          Components: Integration 
    Affects Versions: 7.2.5.Final
            Reporter: Karl von Randow


I use the same Infinispan cache for multiple Hibernate entities. The {{PutFromLoadValidator}} looks for and replaces the {{InvalidationInterceptor}} the first time it sees the cache, but the second time it fails to find the {{InvalidationInterceptor}} and ends up with {{invalidationPosition = 0}} from line 168, which means it incorrectly removes the first interceptor from the chain and then tries to add the {{NonTxInvalidationInterceptor}} again, causing the exception below.

Perhaps the {{NonTxInvalidationInterceptor}} should only be added once per cache, or the {{accessStrategy}} should be cached or something?
