      According to RFC2732 , section 2. Literal IPv6 Address Format in URL's Syntax and HTTP header field definition specification, correct host name and request URL should be enclosed like following one: http://[fe80::56ee:75ff:fe47:c83e].

      In case the Undertow is configured as a static loadbalancer using reverse proxy and client creates request with incorrectly enclosed host name (i.e request for http://fe80::56ee:75ff:fe47:c83e) parsing of address fails with following exception the log.

      10:36:20,823 ERROR [org.xnio.listener] (default I/O-4) XNIO001007: A channel event listener threw an exception: java.lang.NumberFormatException: For input string: ":56ee:75ff:fe47:c83e"

      This happens because enclosed host name is expected.
      Correct format of IPv6 address should be checked and more informative exception should be thrown.
