[infinispan-issues] [JBoss JIRA] Updated: (ISPN-1034) DefaultCacheManager becomes corrupted after component start Exception

DefaultCacheManager becomes corrupted after component start Exception --------------------------------------------------------------------- Key: ISPN-1034 URL: https://issues.jboss.org/browse/ISPN-1034 Project: Infinispan Issue Type: Bug Components: Cache Server Affects Versions: 4.2.1.FINAL Environment: Linux zeus 2.6.35.11-83.fc14.x86_64 #1 SMP Mon Feb 7 07:06:44 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux Reporter: Raman Gupta Assignee: Manik Surtani Priority: Minor Fix For: 4.2.2.BETA1 If Jgroups cluster startup throws an Exception the CacheManager becomes "corrupted", and a retry to get the cache from the CacheManager fails even with the underlying issue removed. For example, with the following code: ============================================================= private Cache initCache(String name) { Cache cache; for(int i = 0; i < 2; i++) { try { System.out.println(i + " cacheManager.getCache"); cache = cacheManager.getCache(name); System.out.println(i + " cache.start()"); cache.start(); System.out.println(i + " done"); return cache; } catch (Exception e) { System.out.println(i + " exception:"); e.printStackTrace(System.out); try { Thread.sleep(5000); } catch (InterruptedException e1) { // ignore } } } return null; } ============================================================= I can get the following output when JGroups does not start (due to an unrelated issue --

attempt, the Exception is no longer the same, but rather a NPE in the DefaultCacheManager. The NPE occurs EVEN WHEN the underlying cause of the first Exception(in my case a network interface that was causing JGroups channel init to fail) has been removed during the sleep time between the attempts, and therefore the program is stuck until a new DefaultCacheManager is created. With a dependency injection approach, creating a new manager for retries is not always feasible or desirable.
