<div class="jive-rendered-content"><div class="logEntry evenRow"><div class="textBlock">I'm looking into JMS message loss issues during shutdown.  I enqueued several thousand mesages into an ESB application.  While the messages were being processed I toggle(stop/start) lifecycle state for the jms listeners via JMX in order to simulate shutdown.  I noticed periodic warnings in the serverlog (listing 1).  The final tally indicated message loss.  I believe I found a bug in ESB. Basically when a doStop (JMXConsole) is called it sets state to STOPPING and immediately terminates the executor thread (MessageAwareListener.java). If the thread was currently processing a mesage bad things happen. I use transcated queues and it appears the JMS message transaction evaporates and the message is lost. I added some code to AbstractThreadedManagedLifecycle.java to remedy the issue.<p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p>AbstractThreadedManagedLifecycle.java<br/>---------------------------------------<br/>protected void doStop()<br/>throws ManagedLifecycleException<br/>{<br/>runningLock.lock() ;<br/>try<br/>{<br/>if (isRunning())<br/>{<br/>setRunning(ManagedLifecycleThreadStatae.STOPPING) ;<br/>}<br/>// Dave Siracusa -start<br/>if (!waitUntilStopped())<br/>{<br/>throw new ManagedLifecycleException("Thread still active!") ;<br/>} // Dave Siracusa - end<p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p>}<br/>finally<br/>{<br/>runningLock.unlock() ;<br/>}<br/>}<p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p>MessageAwareListener.java<br/>---------------------------<br/>protected void doStop()<br/>throws ManagedLifecycleException<br/>{<br/>super.doStop();<br/>_execService.shutdown() ;<br/>}<p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p>Listing 1<br/>----------<br/>2010-09-01 15:04:40,924 WARN [org.jboss.soa.esb.listeners.lifecycle.AbstractThreadedManagedLifecycle] (Thread-200) Unexpected error from doRun()<br/>java.util.concurrent.RejectedExecutionException<br/>at java.util.concurrent.ThreadPoolExecutor$AbortPolicy.rejectedExecutionThreadPoolExecutor.java:1768)<br/>at java.util.concurrent.ThreadPoolExecutor.reject(ThreadPoolExecutor.java:767)<br/>at java.util.concurrent.ThreadPoolExecutor.execute(ThreadPoolExecutor.java:658)<br/>at org.jboss.soa.esb.listeners.message.MessageAwareListener.waitForEventAndProcess(MessageAwareListener.java:359)<br/>at org.jboss.soa.esb.listeners.message.MessageAwareListener.doRun(MessageAwareListener.java:253)<br/>at org.jboss.soa.esb.listeners.lifecycle.AbstractThreadedManagedLifecycle.run(AbstractThreadedManagedLifecycle.java:115)<br/>at java.lang.Thread.run(Thread.java:619)</div></div></div>
