| Error description
Concurrent access to the session object with session traceing
enabled can cause a possible deadlock. Local fixProblem 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 fixPQ63308.jar Comments
