      HttpServletRequestImpl.getParts still checks for the servlet multipart config after parts are already loaded. So if a multipart servlet serves the request and loads the parts successfully and then forwards the request to another non-multipart servlet (like a jsp), some end of request getParts clean up calls can then throw an exception:

      19:00:54,776 WARN  [org.springframework.web.multipart.support.StandardServletMultipartResolver] (default task-1) Failed to perform cleanup of multipart items: java.lang.IllegalStateException: UT010057: multipart config was not present on Servlet

	at jakarta.servlet.api@6.0.0.redhat-00001//jakarta.servlet.http.HttpServlet.service(HttpServlet.java:547)

      In this case, undertow is eagerly checking and throwing the exception for the servlet multipart config (or lack thereof) that it was forwarded to even though we may have already loaded parts by the original servlet, which we can reuse and return.
