8246114: java/net/MulticastSocket/Promiscuous.java fails after 8241072 (multi-homed systems)

[jmtd]

This is a test-only backport. This test fix was merged in 11.0.13-oracle.

The test started to fail in JDK mainline after JDK-8241072, but that change is not in-scope for jdk11u. The test in jdk11u right now passes (for me) before and after applying. The test fix seems reasonable to me despite the failure not triggering in 11u (yet?)

Patch applies clean

[jerboaa]

@jmtd Please use PR title "Backport <sha-of-original-commit>". This will make the bots recognize it properly as a backport (and apply the "clean" label).

[RealCLanger]

Hi Jon,

can you rename the PR title to "Backport <commit hash>" (0f43de9)? That way the bots will pick up the change and recognize it properly as a backport. It would also be nice to enable Github Actions on your repository to have some tier1 test results.

Cheers
Christoph

@jmtd This has some useful info on backporting using the Git workflow: https://wiki.openjdk.java.net/display/JDKUpdates/How+to+contribute+a+fix

[jmtd]

@RealCLanger, @jerboaa thank you for your feedback. I've retitled the PR and enabled actions in my fork (although I haven't imported any actions to it, yet, perhaps I need to do that too. Investigating further).

I've read that, but I hadn't realised that the git commit -m in 2.c) was mandatory rather than illustrative. Noted for next time, thanks!

I assume (since the page doesn't say otherwise) that steps 1-4 are required even for clean backports?

Fixed the test - an IPv4 group cannot be joined from an interface that has no IPv4 address configured

It's not mandatory. But if you use that the default PR title will already what the bots need to recognize the backport pr (as opposed to a, say an 11-only PR). Strictly speaking it's the PR title that matters, not the commit message.

I assume (since the page doesn't say otherwise) that steps 1-4 are required even for clean backports?

Yes. But with Github actions you'd get tier1 testing for free.

@jmtd
Your change (at version 4f2abe4) is now ready to be sponsored by a Committer.

/integrate

Please only integrate once a 11u maintainer reponded on the jdk11u-fix-request label/comment on the bug.

@RealCLanger, @jerboaa thank you for your feedback. I've retitled the PR and enabled actions in my fork (although I haven't imported any actions to it, yet, perhaps I need to do that too. Investigating further).

Now that you have enabled actions, they'll run the next time you push something. The workflow itself is defined in the .github/workflows/submit.yml file of your branch but since you started from a quite current master branch it should be included.
