I have recently installed 2.3.1 after using 2.3 RC4 for the past several months. My testcases are failing using multiple threads. I have observed that multiple threads are using the same cookies. When I run the same testplan using 2.3 RC4, I do not have that problem.
I tried changing to use the different options of the Cookie Manager, but the results were the same -- multiple threads using the same cookies. I determined this by looking at the Cookies using the View Results Tree listener. Woody Aichner
