[ http://jira.jboss.com/jira/browse/JBCACHE-1355?page=all ] Anton Spirkov updated JBCACHE-1355: ----------------------------------- Description: Concurrent Modification Exception appears under load (~500 TPS). We Add, Read and Remove same objects all the time during the tests. The Exception: java.util.ConcurrentModificationException at java.util.HashMap$HashIterator.nextEntry(HashMap.java:793) at java.util.HashMap$KeyIterator.next(HashMap.java:828) at java.util.AbstractCollection.addAll(AbstractCollection.java:305) at java.util.HashSet.<init>(HashSet.java:100) at org.jboss.cache.UnversionedNode.getKeysDirect(UnversionedNode.java:433) at org.jboss.cache.interceptors.CacheLoaderInterceptor.mustLoad(CacheLoaderInterceptor.java:303) at org.jboss.cache.interceptors.CacheLoaderInterceptor.loadIfNeeded(CacheLoaderInterceptor.java:168) at org.jboss.cache.interceptors.CacheLoaderInterceptor.invoke(CacheLoaderInterceptor.java:157) at org.jboss.cache.interceptors.ActivationInterceptor.invoke(ActivationInterceptor.java:67) at org.jboss.cache.interceptors.Interceptor.invoke(Interceptor.java:76) at org.jboss.cache.interceptors.UnlockInterceptor.invoke(UnlockInterceptor.java:37) at org.jboss.cache.interceptors.Interceptor.invoke(Interceptor.java:76) at org.jboss.cache.interceptors.PessimisticLockInterceptor.invoke(PessimisticLockInterceptor.java:203) at org.jboss.cache.interceptors.Interceptor.invoke(Interceptor.java:76) at org.jboss.cache.interceptors.NotificationInterceptor.invoke(NotificationInterceptor.java:32) at org.jboss.cache.interceptors.Interceptor.invoke(Interceptor.java:76) at org.jboss.cache.interceptors.TxInterceptor.handleNonTxMethod(TxInterceptor.java:298) at org.jboss.cache.interceptors.TxInterceptor.invoke(TxInterceptor.java:131) at org.jboss.cache.interceptors.Interceptor.invoke(Interceptor.java:76) at org.jboss.cache.interceptors.CacheMgmtInterceptor.invoke(CacheMgmtInterceptor.java:81) at org.jboss.cache.interceptors.Interceptor.invoke(Interceptor.java:76) at org.jboss.cache.interceptors.InvocationContextInterceptor.invoke(InvocationContextInterceptor.java:62) at org.jboss.cache.CacheImpl.invokeMethod(CacheImpl.java:3939) at org.jboss.cache.CacheImpl.get(CacheImpl.java:1441) at org.jboss.cache.CacheImpl.get(CacheImpl.java:1415) Please don't hesitate to contact me for additional information.
