@manusa I think we will need this for our next release of Keycloak, so we'll probably need this in Quarkus 3.15.x.

[manusa]

Should we backport the fix to 6.13 then?

(I'm assuming this based on https://github.com/quarkusio/quarkus/blob/7c367ac49c2f617b6e348247d5b219e91a993f34/pom.xml#L72)

[shawkins]

Should we backport the fix to 6.13 then?

Yes, I believe that is still the target release.

[vmuzikar]

We need it in Quarkus 3.20, as IPv6 isn't coming until Keycloak 26.2.

[manusa]

So no back-port + release needed then?

If that's the case, I can prioritize releasing 7.1 (which was the original plan for next week).

Also, @shawkins, I'd need your input for #6792, to see if we need to do something there or leave it as is.

I'm not sure which version Quarkus 3.20, especially JOSDK will use. CC @metacosm
