> I had written a unit test which was running successfully until I turned on DEBUG level in log4j. This caused the unit test to fail and I tracked down the problem to the ParametersInterceptor, line 241 in xwork-2.0.4.jar: 
> logEntry.append(String.valueOf(valueArray[valueArray.length - 1]));
> The value array there can be empty (0-length) and that line will try to access valueArray[-1] which causes the exception. 
> I don't know if the user can submit input that would result in a request parameter with an empty array, so this might not be an issue in production applications, but I think it should be fixed for the sake of making the ParametersInterceptor more robust, in case anyone wants to test request parameters with empty arrays.
