>From a purely theoretical perspective, it is valid for two threads to call getParameterMap() (and therefore isLocked()), once the ParameterMap has been established. Probably not a concern in the real world. Since the only call to ParameterMap.isLocked() comes from Request.getParameterMap(), I'd put the saving of the calling Thread object in a synchronized block there, along with a check to insure no other thread had been there. In addition, I would also save the array returned by getStackTrace() (assuming you're running on SE 5) to provide some context for the call. This would also help to widen the window and hopefully cause the problem to occur sooner. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
