Potential concurrency issues when retrieving a cache concurrently (for the first time)
--------------------------------------------------------------------------------------

                 Key: ISPN-1051
                 URL: https://issues.jboss.org/browse/ISPN-1051
             Project: Infinispan
          Issue Type: Bug
            Reporter: Emmanuel Bernard
            Assignee: Manik Surtani


My code initialize the CacheManager but retrieve the cache only "on demand". Several threads do access cacheManager.getCache(namedCache); concurrently.

I am experiencing the following exceptions
