Brian Stansberry commented on WFLY-5892:
----------------------------------------
FWIW, here's a bit of argument that this is a VM bug that I did on a similar issue, WFCORE-934. In that case it was just affecting a test case so we were willing to hack the test to not execute the problem test if the relevant NetworkInterface is virtual and thus made the problem go away. But production code is a different beast. My comment on the other issue:
"
Looks like a JVM problem then. InetAddress.getByName("fe80:0:0:0:8:20ff:fe6d:eab0%net0:2") is not behaving in accordance with javadoc. It is throwing UnknownHostException when it should not. For a literal IPv6 address string that represents a link-local or site-local it should only check the validity of the address format. The format is valid, as described at https://docs.oracle.com/javase/8/docs/api/java/net/Inet6Address.html#scoped which is linked in the InetAddress.getByName javadoc.
For an IPv6 literal address string with a scope_id appended, UnknownHostException should only be thrown if the address isn't a site-local or link-local address.
This test passes in the community CI runs: http://brontes.lab.eng.brq.redhat.com/project.html?projectId=WildFlyCore&testNameId=5354999289145404852&tab=testDetails
There have been failures in the past. I haven't examined them all, but it looks like the failures were due to incorrectly testing global IPv6 addresses, which my patch fixed.
What's happening here is for an InetAddress 'address' obtained from inspecting the addresses available on the system, InetAddress.getByName(address.getHostAddress()) is throwing an UnknownHostException. That's clearly wrong.
