    Description

      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.

          Enhancement - An enhancement to or refactoring of existing functionality that is not configurable by an end user (typically a change made by an internal team that affects users) UNDERTOW-1108 Warning when IPv6 address in not correctly encolsed

          • Minor - To be worked after urgent, high, and medium priorities are resolved. This term is chosen when the severity of the issue is low, or the complexity or effort to correct it may be higher, relatively speaking. For low priority issues, known workarounds exist or are not needed due to the trivial effort needed to address the issue.

          Component Upgrade - A task tracking an update to a bundled component or revision of component upstream of the project. JBEAP-11706 Undertow 1.4.17.Final

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
