commit a91c3000b2a2ea1de8d9f41aeaf30692088e2462 Author: Robert Lazarski <[email protected]> AuthorDate: Mon Apr 20 10:59:41 2026 -1000 AXIS2-5858 Bracket IPv6 addresses in soap:address location URLs When the detected IP address is IPv6 (contains ':'), wrap it in brackets per RFC 2732. Without this, a soap:address like http://fe80::1:8080/services/MyService is invalid — it should be http://[fe80::1]:8080/services/MyService. The IPv6-aware IP detection in Utils.getIpAddress() (which prefers IPv4 for backward compatibility) was contributed by Christian Ortlepp in PR #842. This commit adds the URL formatting fix that completes the IPv6 support.
