Exception thrown when connecting to a pre-exisiting cache --------------------------------------------------------- Key: JBCACHE-1213 URL: http://jira.jboss.com/jira/browse/JBCACHE-1213 Project: JBoss Cache Issue Type: Bug Security Level: Public (Everyone can see) Components: Replication Affects Versions: 2.0.0.GA Environment: JBoss cache 2.0.0GA; Dependancies according to POM excluding JGroups, using JGroups 2.5.0GA; WinXP SP2. Javba 1.6.0_02 Reporter: Carl Shelbourne Assigned To: Manik Surtani Priority: Minor When attempting to connect to an existing cache, the following exceptions are thrown. The exception appears to be thrown before the cache state has transferred to started from either created or starting. This exception is only seen once we have connected to a cache, disconnected from the cache, then subsequently reconnected re-using the same Cache instance object. When the client disconnects it call Cache.stop(). The following method is used to get the cache: private Cache getTreeCache() { if ( _treeCache != null ) { if ( _treeCache.getCacheStatus() == CacheStatus.DESTROYED ) { _treeCache.create(); _treeCache.start(); } else if ( _treeCache.getCacheStatus() == CacheStatus.CREATED ) { _treeCache.start(); } } return _treeCache; } And we call this to close the cache once the client has finished with it. Please note other clients will most probably still be connected to the cache ensuring the cache state is maintained public void destroy() { if ( _treeCache != null ) { _treeCache.stop(); _treeCache.destroy(); } } the cache is initially create with: ... CacheFactory factory = DefaultCacheFactory.getInstance(); ... Cache cache = factory.createCache( config, false ); ...
