Hi all, I'm attempting to browse the DLQ in Jboss MQ in order to log the messages for inspection and review by our developers. I'm getting a very strange error when I try to get an enumeration. I'm connecting to remote queue via JNDI
Enumeration queueContents = browser.getEnumeration(); Causes the following error below. I'm assuming this is a duplicate hashcode issue, but how can I change the implementation so that collisions don't occur? | org.jboss.mq.SpyJMSException: Cannot browse the Queue; - nested throwable: (java.lang.RuntimeException: Can't add object '2 msg=232 STORED PERSISTENT queue=QUEUE.DLQ priority=4 lateClone=false hashCode=22159791' to LRUCache that is already in cache.) | at org.jboss.mq.SpyJMSException.getAsJMSException(SpyJMSException.java:66) | at org.jboss.mq.SpyJMSException.rethrowAsJMSException(SpyJMSException.java:51) | at org.jboss.mq.Connection.browse(Connection.java:861) | at org.jboss.mq.SpyQueueBrowser.getEnumeration(SpyQueueBrowser.java:83) | at com.purdueefcu.statements.writer.jms.QueueInspectorImpl.getQueueContents(QueueInspectorImpl.java:81) | at com.purdueefcu.statements.writer.jms.QueueInspectorImpl.getFailedProcessMessages(QueueInspectorImpl.java:41) | at com.purdueefcu.statements.QueueInspectorTest.testGetFailedProcessMessages(QueueInspectorTest.java:16) | at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) | at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:585) | at junit.framework.TestCase.runTest(TestCase.java:154) | at junit.framework.TestCase.runBare(TestCase.java:127) | at org.springframework.test.ConditionalTestCase.runBare(ConditionalTestCase.java:69) | at junit.framework.TestResult$1.protect(TestResult.java:106) | at junit.framework.TestResult.runProtected(TestResult.java:124) | at junit.framework.TestResult.run(TestResult.java:109) | at junit.framework.TestCase.run(TestCase.java:118) | at junit.framework.TestSuite.runTest(TestSuite.java:208) | at junit.framework.TestSuite.run(TestSuite.java:203) | at org.eclipse.jdt.internal.junit.runner.junit3.JUnit3TestReference.run(JUnit3TestReference.java:130) | at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) | at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:460) | at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:673) | at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:386) | at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:196) | Caused by: java.lang.RuntimeException: Can't add object '2 msg=232 STORED PERSISTENT queue=QUEUE.DLQ priority=4 lateClone=false hashCode=22159791' to LRUCache that is already in cache. | at org.jboss.mq.server.MessageCache$LRUCache.addMostRecent(MessageCache.java:791) | at org.jboss.mq.server.MessageCache.messageReferenceUsedEvent(MessageCache.java:401) | at org.jboss.mq.server.MessageReference.getMessage(MessageReference.java:168) | at org.jboss.mq.server.MessageReference.getMessageForDelivery(MessageReference.java:147) | at org.jboss.mq.server.BasicQueue.browse(BasicQueue.java:509) | at org.jboss.mq.server.JMSQueue.browse(JMSQueue.java:161) | at org.jboss.mq.server.JMSDestinationManager.browse(JMSDestinationManager.java:597) | at org.jboss.mq.server.JMSServerInterceptorSupport.browse(JMSServerInterceptorSupport.java:136) | at org.jboss.mq.security.ServerSecurityInterceptor.browse(ServerSecurityInterceptor.java:99) | at org.jboss.mq.server.TracingInterceptor.browse(TracingInterceptor.java:418) | at org.jboss.mq.server.JMSServerInvoker.browse(JMSServerInvoker.java:142) | at org.jboss.mq.il.uil2.ServerSocketManagerHandler.handleMsg(ServerSocketManagerHandler.java:116) | at org.jboss.mq.il.uil2.SocketManager$ReadTask.handleMsg(SocketManager.java:395) | at org.jboss.mq.il.uil2.msgs.BaseMsg.run(BaseMsg.java:398) | at EDU.oswego.cs.dl.util.concurrent.PooledExecutor$Worker.run(PooledExecutor.java:748) | at java.lang.Thread.run(Thread.java:595) | | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4112591#4112591 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4112591 _______________________________________________ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
