[jboss-jira] [JBoss JIRA] (JBMESSAGING-1747) ClassNotFoundException while consuming a message in a JMS Queue

ClassNotFoundException while consuming a message in a JMS Queue --------------------------------------------------------------- Key: JBMESSAGING-1747 URL: https://issues.jboss.org/browse/JBMESSAGING-1747 Project: JBoss Messaging Issue Type: Bug Components: JMS Destination Manager Affects Versions: 1.4.1.GA Environment: Jboss version : 5.0.1 GA Reporter: Stephan Lagraulet Assignee: Yong Hao Gao Fix For: 1.4.0.SP3.CP15, 1.4.8.SP7 We have several JMS queues setup on our jboss server. We are using spring to handle the messages. When several clients simultaneously post some messages in different queues, the consumer doesn't find the class for the task, ending with this stack trace: 2009-07-28 17:10:21,089 WARN [SimpleMessageListenerContainer] [] - Execution of JMS message listener failed java.lang.RuntimeException: fr.billetel.interfaces.ws.allotement.business.etatventes.request.CodificationsTaskRequest at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:252) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:247) at org.jboss.classloader.spi.base.BaseClassLoaderDomain.loadClass(BaseClassLoaderDomain.java:279) at org.jboss.classloader.spi.base.BaseClassLoaderDomain.loadClass(BaseClassLoaderDomain.java:1102) at org.jboss.classloader.spi.base.BaseClassLoader.loadClassFromDomain(BaseClassLoader.java:772) at org.jboss.classloader.spi.base.BaseClassLoader.loadClass(BaseClassLoader.java:415) at java.lang.ClassLoader.loadClass(ClassLoader.java:252) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320) We debugged the class org.jboss.messaging.util.OrderedExecutorFactory, and it appears that the class doesn't have the right classloader as it reuses a thread previously setup with an other classloader (the application is packaged in different ears while the queues are defined in deploy), ending in this exception. For the moment, we patched the code so that the classloader is reloaded for every call, but it does not seem like a good solution on a long term.
