I have a Seam web app with two SFSB's (one injected into the other). When the ejb container (JBoss 4.2.1.GA) passivates the SFSB's and I run a test case, I get a log4j related SerializationException caused by InstantiationException.
"Thrown when an application tries to create an instance of a class using the newInstance method in class Class, but the specified class object cannot be instantiated because it is an interface or is an abstract class." http://java.sun.com/j2se/1.4.2/docs/api/java/lang/InstantiationException.html I removed all references to the Seam @Logger and Log in my SFSB's. I can still reproduce the exception. Any ideas on this? It's difficult to do root cause analysis b/c the ejb container is using an algorithm possibly, like LRU or MRU, to determine when to evict the SFSB's from memory and serialize appropriately. Any way to change this timeout or algorithm to speed up testing?? thx. 14:28:58,599 ERROR [ContextualHttpServletRequest] ended request due to exception | java.lang.reflect.InvocationTargetException |
