This backport pull request has now been updated with issue from the original commit.

runtime/containers/docker/TestCPUAwareness.java failure in the Pre-submit tests - Linux x64 - Test (tier1) (and the 32-bit version) in GHA are failing on other PRs so is not related to this change and can therefore be ignored.

I am not a Reviewer in jdk8u but to gain experience of doing so I've reviewed this change.

The PR is not labelled "clean" but I'm not sure why, the patch is identical to that in 11u and applies with no fuzz.

As @sxa notes the pre-submit failure is an issue in the main 8u tree at the moment and is not specific to this change.

Test-only change. I've run it and it passes for me after this patch, although I haven't done a battery of runs to aggregate the results, like the backporter has.

runtime/containers/docker/TestCPUAwareness.java failure

That is https://bugs.openjdk.org/browse/JDK-8370492 and a combination that --cpu-shares=1023 back-mapping to the default 100 with the new mapping function. So a value of --cpu-shares=1000 (mapping to 99) should be chosen for the test.

Path in JDK 11 is test/jdk/sun/net/www/http/KeepAliveCache/KeepAliveProperty.java. JDK 8 path is jdk/test/sun/net/www/http/KeepAliveCache/KeepAliveProperty.java. I.e. test/jdk vs. jdk/test.

Path in JDK 11 is test/jdk/sun/net/www/http/KeepAliveCache/KeepAliveProperty.java. JDK 8 path is jdk/test/sun/net/www/http/KeepAliveCache/KeepAliveProperty.java. I.e. test/jdk vs. jdk/test.

Thanks... I had to read your comment twice to see the difference!

[sxa]

Is there anything else I need to do because it's not considered clean, or is that up to the reviewers?

[jerboaa]

Looks good. Clean after path unshuffeling.

[sxa]

/approval request test-only backport, clean after path unshuffling, tests pass
