"Singleton not set for ModuleClassLoader for Module" exception occurs when a process starts or a task completes
Even though this exception occurs, the process instance has been started and the first task is assigned to the particular user. However, I cannot complete a task from another jsp page because of this exception. This does not occur for the very first time after restarting the jboss. I am struggling with this for some time. Any help is highly appeciated.
