      1. Enable the AJP listener:

      /subsystem=undertow/server=default-server/ajp-listener=ajp-test:add(socket-binding=ajp)

      2. Access the AJP port:

      curl localhost:8009

      You should see the ERROR in the server log.
      Note: The request is expected to fail, but there should be no errors, just a BadRequestException at DEBUG level (see JBEAP-10151)

    Description

      Sending an incorrect AJP request to the AJP listener causes a NPE:

      ERROR [io.undertow.request.io] (default I/O-7) UT005090: Unexpected failure: java.lang.NullPointerException

      The getRequestMethod() call in HttpServerExchange returns null .

      This is a regression in Undertow 2.0.30.SP2. Seems to be caused by the fix for JBEAP-19204

          • Blocker - To be worked above all other priorities. This term is chosen when the severity of the issue is very high, has no workaround, or the effort for the change is comparatively low. Issues that may be very publicly visible and could generate significant media attention may also drive a higher priority.
