Sorry I've checked a bug in a commit I've fixed earlier.(https://github.com/spring-projects/spring-framework/pull/26905) This bug was reported in #26910. If there are'Url Query' and'Url Fragments', it is a normal case, but a bug occurs. I have fix this.

This causes another problem, if by mistake a a uri like this is built: http://localhost:8085api/something (missing slash between the port and the path), the previous regex would still extract the correct port number and path. However with this change, it will extract 8085api as the port and of course will throw a NumberFormatException.
