Naming lookup intermittently fails on IBM JDK due to org.jboss.remoting3.NotOpenException: Endpoint is not open. ---------------------------------------------------------------------------------------------------------------- Key: WFLY-1149 URL: https://issues.jboss.org/browse/WFLY-1149 Project: WildFly Issue Type: Feature Request Components: Naming, Test Suite Environment: IBM JDK 6 (build 20110203_074623) IBM JDK 7 (build 20120809_118929) Reporter: Ivo Studensky Attachments: endpoint_is_not_open_2012-11-26.xml, failed_with_status_cancelled_2012-11-26.xml, test_output_with_trace_logging_in_EndpointCache.xml RemoteNamingTestCase intermittently fails when running on IBM JDK. According to logs the remoting channel had been closed before the endpoint tried to connect to it. Unfortunately, when I was trying to debug this issue the tests always nicely passed. test.log snippet: {noformat} 13:16:31,115 DEBUG [org.xnio.nio] (Remoting "config-based-naming-client-endpoint" read-1) Started channel thread 'Remoting "config-based-naming-client-endpoint" read-1', selector sun.nio.ch.EPollSelectorImpl@345642e1 13:16:31,115 DEBUG [org.xnio.nio] (Remoting "config-based-naming-client-endpoint" write-1) Started channel thread 'Remoting "config-based-naming-client-endpoint" write-1', selector sun.nio.ch.EPollSelectorImpl@1dc68cf2 13:16:31,121 DEBUG [org.jboss.naming.remote.client.InitialContextFactory] (main) jboss.naming.client.connect.options. has the following options {org.xnio.Options.SASL_POLICY_NOPLAINTEXT=>false} 13:16:31,191 ERROR [org.jboss.naming.remote.protocol.v1.RemoteNamingStoreV1] (Remoting "config-based-naming-client-endpoint" task-1) Channel end notification received, closing channel Channel ID d1f17196 (outbound) of Remoting connection fd3dcedc to /127.0.0.1:4447 13:16:31,204 DEBUG [org.jboss.naming.remote.client.HaRemoteNamingStore] (main) Failed to connect to server remote://127.0.0.1:4447: org.jboss.remoting3.NotOpenException: Endpoint is not open at org.jboss.remoting3.EndpointImpl.resourceUntick(EndpointImpl.java:182) at org.jboss.remoting3.EndpointImpl.doConnect(EndpointImpl.java:261) at org.jboss.remoting3.EndpointImpl.doConnect(EndpointImpl.java:251) at org.jboss.remoting3.EndpointImpl.connect(EndpointImpl.java:349) at org.jboss.remoting3.EndpointImpl.connect(EndpointImpl.java:333) at org.jboss.naming.remote.client.EndpointCache$EndpointWrapper.connect(EndpointCache.java:105) at org.jboss.naming.remote.client.HaRemoteNamingStore.failOverSequence(HaRemoteNamingStore.java:179) at org.jboss.naming.remote.client.HaRemoteNamingStore.namingOperation(HaRemoteNamingStore.java:117) at org.jboss.naming.remote.client.HaRemoteNamingStore.lookup(HaRemoteNamingStore.java:223) at org.jboss.naming.remote.client.RemoteContext.lookup(RemoteContext.java:79) at org.jboss.naming.remote.client.RemoteContext.lookup(RemoteContext.java:83) at javax.naming.InitialContext.lookup(InitialContext.java:422) at org.jboss.as.test.integration.naming.remote.simple.RemoteNamingTestCase.testRemoteLookup(RemoteNamingTestCase.java:74) {noformat} server.log snippet: {noformat} 13:16:31,025 INFO [org.jboss.as.server] (management-handler-thread - 3) JBAS018559: Deployed "test.jar" 13:16:31,163 DEBUG [org.jboss.naming.remote.server.RemoteNamingService] (Remoting "thinkpax" task-3) Channel Opened - Channel ID 51f17196 (inbound) of Remoting connection b9da2788 to /127.0.0.1:46866 13:16:31,176 DEBUG [org.jboss.naming.remote.server.RemoteNamingService] (Remoting "thinkpax" task-4) Chosen version 0x01 13:16:31,189 DEBUG [org.jboss.naming.remote.server.RemoteNamingService] (Remoting "thinkpax" read-1) Channel Channel ID 51f17196 (inbound) of Remoting connection b9da2788 to /127.0.0.1:46866 closed. 13:16:31,193 INFO [org.jboss.as.naming] (Remoting "thinkpax" task-1) JBAS011806: Channel end notification received, closing channel Channel ID 51f17196 (inbound) of Remoting connection b9da2788 to null {noformat}
