Producer Method and java.io.NotSerializableException

Steve Hostettler Newbie



There is something that I can really understand in my project. I get a java.io.NotSerializableException exception when Tomcat shuts down.



WARNING: Cannot serialize session attribute org.jboss.weld.context.ConversationContext.1#org.jboss.weld.bean-flat-ManagedBean-class ch.demo.web.ManageStudentRegistration for session 91DA3D803BD3BC86DCF7C5FF6BF6F942
java.io.NotSerializableException: java.util.logging.Logger
          at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1164)
          at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1518)
          at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:{1483)



My managed bean has a logger field which is transient:



public class ManageStudentRegistration implements Serializable {

 private static final long serialVersionUID = 2123342218792192804L; 
 private transient Logger mLogger;




The producer for the logger looks like:



public class LoggerProducer  implements Serializable {

    private static final long serialVersionUID = -7352371086416154400L;

    public Logger getLogger(final InjectionPoint injectionPoint) {
        return LoggerFactory.getLogger(injectionPoint.getBean().getBeanClass());





I do not understand what field it tries to serializable as the mLogger is transient.


In debug mode I get the following output from ObjectOutputStream.writeObject:


Bean: Producer Method [Logger] with qualifiers [@Any @Default] declared as [[method] @Produces public ch.demo.helpers.LoggerProducer.getLogger(InjectionPoint)]; Instance: org.slf4j.impl.JDK14LoggerAdapter(ch.demo.web.ManageStudentRegistration); CreationalContext: org.jboss.weld.context.CreationalContextImpl@17e34309



Obviously the problem is in the producer not in the member field mLogger.


Did I miss something obvious?


Many thanks in advance for your help
