![]() APAR status Closed as program error. Error description Concurrent access to the session object with session traceing enabled can cause a possible deadlock.Local fix Problem summary **************************************************************** * USERS AFFECTED: WebSphere Application Server -- Session * * Manager Users * **************************************************************** * PROBLEM DESCRIPTION: With Session Tracing enabled, * * deadlocks are being seen when the * * session object was being accessed in * * the toString() method of custom * * defined object bound into the session * * object. * **************************************************************** * RECOMMENDATION: * **************************************************************** With session tracing enabled, the session manager prints out the contents of the session manager by invoking the toString() method on the session object. This in turn causes the toString() method of all the objects bound to the session object to be invoked. If one of these objects in its toString() method accesses the session object, for example by calling the session.getAttribute() method and there are concurrent requests for the same session object, a deadlock can occur between the two threads serving the concurrent requests. This problem will happen only if session tracing is enabled and the objects bound to the session object access the session object in their toString method().Problem conclusion This fix will prevent the deadlock described in the problem summary from occuring.Temporary fix PQ63308.jarComments
