[infinispan-issues] [JBoss JIRA] Updated: (ISPN-1384) Remote processes can access cache before it's started

Remote processes can access cache before it's started ----------------------------------------------------- Key: ISPN-1384 URL: https://issues.jboss.org/browse/ISPN-1384 Project: Infinispan Issue Type: Bug Affects Versions: 5.0.1.FINAL Reporter: Michal Linhard Assignee: Galder Zamarreño Fix For: 5.1.0.BETA1, 5.1.0.FINAL Attachments: edg-thread-problem.zip version: Infinispan 5.1.0-SNAPSHOT last commit fc94449eec33469057614a13cbfe59e4f4e855fd Author: Michal Linhard <michal(a)linhard.sk&gt; Date: Wed Sep 7 13:42:32 2011 +0200 The mechanism that locks cache while it is being created and started is not in effect when accessing the cache remotely. The problem happens in this scenario: 1. Thread1 does DefaultCacheManager.getCache and starts the cache to the point where ComponentRegistry for that cache exists, but the cache is not yet started 2. Thread2 (originating in JGroups layer) does call via InboundInvocationHandlerImpl and gets hold of the ComponentRegistry for the cache and calls perform() on the command (note that the Thread2 doesn't obtain the cache via DefaultCacheManager.getCache and therefore it doesn't have to wait on the cacheCreateLock or CacheWrapper lock) the problem manifests itself in JBPAPP-7173 where using unstarted CacheLoaderInterceptor leads to NPE.
