      1)deploy a REST service that accepts GET requests and evaluates an http parameter, e.g.:
      @GET
      @Path("/service")
      public Response service(@PathParam("query-string") String queryString);

      2)send a request with one or more invalid characters in the http parameter, e.g.:
      http://..../service?query-string=1|2}

    Description

      Test case:
      an HTTP Request contains invalid characters in the value of an expected http parameter, for example:
      http://....?parameter=},xyz{|i

      Effect:
      The correct response code should be just a simple 400 Bad Request but on the other hand RESTEasy returns an HTTP Status 500 response with a NullPointerException stacktrace in the response body.
      From the error logs it is visible that the NullPointerException is being caused by URI creation failing:
