ActionBean instances are not threadsafe. You've already identified the cause: the request parameters are bound to the ActionBean instances. The result is that each ActionBean instane is tied to the request it handles. Currently, Stripes instantiates an ActionBean for each request. Note that it is possible to pool ActionBean instances; this is just not the current implementation. > Using JMeter I get multiple threads(users) calling common Stripes Action > Beans with different values in the request parameters.

One of the mistakes I used to make is that I didn't log enough information to uniquely identify the context where my code was running. In your case, I'd ensure that each bit of information you collect is associated with the HTTP request and thread handling that request. It may provide more information than you have now.
