One of our applications, currently in production with jboss-3.2.3, is occasionally throwing "Could not load field value: xxxxx" exceptions like the one below when deployed with jboss-3.2.4. The exceptions are unpredictable and mostly disappear on the next similar request. Any help will be appreciated.
