The latest AvailableProcessors failure on JDK25 for aarch64 Linux is this one:

I'm adding this here to differentiate this issue from #4228

Also, this issue has been seen on JDK8 here: https://ci.adoptium.net/job/Test_openjdk8_hs_extended.openjdk_aarch64_linux_testList_0/54/consoleFull

• Failing node: test-docker-ubi9-armv8-2
• Passing node: test-osuosl-ubuntu2404-aarch64-1

And here's an upstream issue that has a similar symptom: https://bugs.openjdk.org/browse/JDK-8380316

Update: Instances of node-specific AvailableProcessors failure are seen on Jdk8 and 17, but not 11.

Running a grinder to check if JDK11 fails on a known failing machine: https://ci.adoptium.net/job/Grinder/16873/console
It did. Test fails on affected docker nodes across all jdk versions.

JDK21:

• Fail: test-docker-fedora42-armv8-1
• Pass: test-docker-ubuntu2404-armv8-5
