WLS 9.2 MP3 - Serialization/Deserialization java.lang.ClassNotFoundException
(Doc ID 1075071.1)
Last updated on AUGUST 03, 2023
Applies to:
Oracle WebLogic Server - Version 9.2 to 10.3.2Information in this document applies to any platform.
Symptoms
An equinox framework (based on OSGi framework) in a non clustered environment is being used that has session persistence turned off (say just a single server). The equinox core servlet uses the code snippet where it is loading the class within the thread scope and creating a session attribute within the same thread scope. After 10 seconds customer is invalidating the sessions. At this point WebLogic server uses a different thread to invalidate the session. Since the new thread doesn't know about the other thread scope, it fails to deserialize and a "ClassNotFound" exception is found.
