I used sleep() as you can see in the modified version of
getParameterMap() at the end of this message.
I got the issue and here is the trace.
What I call "original thread" is the one that was the first to call
Requuest.getParameterMap()
Correct me if I am wrong but it seems to me that the 2 threads are from
Tomcat, not from our application.
