I have the same problem. When the last node in FQN is a String everything is fine. But when the last node in FQN is an Integer the cache is not cleared. | treeCache.put(new Fqn(new Object[]{"a", "b", Integer.valueOf(1).toString()}), "key2", "value2");//The data will be cleared | | treeCache.put(new Fqn(new Object[]{"a", "b", Integer.valueOf(1)}), "key2", "value2");//The data will not be cleared The logs are the same in both cases | 2006-08-21 10:52:02,692 TRACE [org.jboss.cache.eviction.LRUAlgorithm] Node /a/b/1 should be evicted because of max age | 2006-08-21 10:52:02,692 TRACE [org.jboss.cache.eviction.BaseEvictionAlgorithm] Attempting to evict cache node with fqn of /a/b/1 | 2006-08-21 10:52:02,692 TRACE [org.jboss.cache.interceptors.TxInterceptor] (null) call on method [_evict(/a/b/1)] | 2006-08-21 10:52:02,692 TRACE [org.jboss.cache.interceptors.PessimisticLockInterceptor] PessimisticLockInterceptor invoked for method _evict(/a/b/1) | 2006-08-21 10:52:02,692 TRACE [org.jboss.cache.interceptors.PessimisticLockInterceptor] Attempting to lock node /a/b/1 for owner Thread[Timer-5,5,jboss] | 2006-08-21 10:52:02,692 TRACE [org.jboss.cache.Node] acquiring RL: fqn=/a, caller=Thread[Timer-5,5,jboss], lock=<unlocked> | 2006-08-21 10:52:02,692 TRACE [org.jboss.cache.Node] acquired RL: fqn=/a, caller=Thread[Timer-5,5,jboss], lock=read owners=[Thread[Timer-5,5,jboss]] | 2006-08-21 10:52:02,692 TRACE [org.jboss.cache.Node] acquiring RL: fqn=/a/b, caller=Thread[Timer-5,5,jboss], lock=<unlocked> | 2006-08-21 10:52:02,692 TRACE [org.jboss.cache.Node] acquired RL: fqn=/a/b, caller=Thread[Timer-5,5,jboss], lock=read owners=[Thread[Timer-5,5,jboss]] | 2006-08-21 10:52:02,692 TRACE [org.jboss.cache.Node] acquiring WL: fqn=/a/b/1, caller=Thread[Timer-5,5,jboss], lock=<unlocked> | 2006-08-21 10:52:02,692 TRACE [org.jboss.cache.Node] acquired WL: fqn=/a/b/1, caller=Thread[Timer-5,5,jboss], lock=write owner=Thread[Timer-5,5,jboss] | 2006-08-21 10:52:02,692 TRACE [org.jboss.cache.interceptors.CallInterceptor] Invoking method _evict(/a/b/1) on cache. | 2006-08-21 10:52:02,692 TRACE [org.jboss.cache.TreeCache] _evict(/a/b/1) | 2006-08-21 10:52:02,692 TRACE [org.jboss.cache.TreeCache] _remove(null, "/a/b/1") | 2006-08-21 10:52:02,692 TRACE [org.jboss.cache.AbstractNode] removed child 1 | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3966381#...
