Thanks for all replies, you have convinced me that we should investigate further.
I propose to implement a bug catcher in Tomcat ParameterMap by storing the thread that called the constructor amd then check its invariance when calling other methods (e.g. isLocked) of this class, if the invariance is violated we will throw an exception. It seems to me that with this data, we should be able to determine which code is accessing the map and so we should know whether it's a bug in the application or not. Any other suggestion?
