           Summary: ThreadUsecaseResource: error when accessing request
           Product: Yanel
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal (C)
          Priority: P2
         Component: General

The lifetime of a HttpServletRequest expires when the service() method of the
servlet is finished.
This means that accessing the request object from a background thread yields
unpredictable results.

e.g. the following exception may occur:

Caused by: java.lang.NullPointerException
