[infinispan-dev] update page on custom interceptors

Hi, I've added a sanity check to verify weather all the CacheManagers created by a test are being shutdown within the same test[1]. The cool part is that if a CM is not being closed, the fwk will report you where the unclosed CacheManager was created (java file and line, see bellow), so that you don't have to spend too much time looking into code ;) E.g. [pool-2-thread-7] Test testTxChangesOnAtomicMap(org.infinispan.atomic.AtomicMapFunctionalTest) succeeded. Test suite progress: tests succeeded: 179, failed: 1, skipped: 0. [pool-2-thread-7] Test testTxChangesOnAtomicMapNoLocks(org.infinispan.atomic.AtomicMapFunctionalTest) succeeded. Test suite progress: tests succeeded: 180, failed: 1, skipped: 0. !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!! (pool-2-thread-7) Exiting because atomic.AtomicMapFunctionalTest has NOT shut down all the cache managers it has started !!!!!!! !!!!!! (pool-2-thread-7) The still-running cacheManager was created here: org.infinispan.atomic.AtomicMapFunctionalTest.setUp(AtomicMapFunctionalTest.java:33) !!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
