createVariableInstance trying to serialize Hibernate objects ------------------------------------------------------------ Key: JBPM-471 URL: http://jira.jboss.com/jira/browse/JBPM-471 Project: JBoss jBPM Issue Type: Bug Components: Core Engine Reporter: Derek Cornelius Assigned To: Tom Baeyens If an object is loaded by Hibernate that does not implement Serializable and then a variable instance is created, JBPM will try to serialize the object which causes and exception. If the Hibernate object is Serializable, then the JBPM serializes the Hibernate session information. When the object is reloaded, exceptions occurs when the lazily loaded collections are accessed or the CGLib generated class does not exist. Looks like the problem is in createVariableInstance, the check should be done for Hibernate objects before Serializable objects.
