wiremock-jetty12: NullPointerException within WireMockHandlerDispatchingServlet (similar to #1224)

[finalchild]

Proposal

Using wiremock-jetty12. Doesn't happen in wiremock-standalone.

After the first test (that is, mockServer.start() -> stubFor() -> resetAll() -> stop() -> start() -> stubFor()), WireMockHandlerDispatchingServlet fails to initialize requestHandler to non-null, making the requests return 500 from second tests onward.

requestHandler = (RequestHandler) context.getAttribute(handlerClassName);

This returns null.

Reproduction steps

I'm too busy debugging all the issues from upgrading our dependencies right now. I'll try to provide minimal reproduction code soon.

Thanks for reporting. Will await the repro case.
