The latest arm failure on jdk8 for AvailableProcessors is this one:

Adding this comment to help differentiate this issue from #4100

Symptom seen on JDK11 arm32 tests:
adoptium/aqa-tests#7599 (comment)

Rerun passed on test-docker-ubuntu2404-armv7-9, and the original failed twice on test-docker-ubuntu2404-armv7-10.

AvailableProcessors.jtr.txt - jtr from failed run.

[adamfarley]

Passes on JDK17:

• test-docker-ubuntu2404-armv7-10 - https://ci.adoptium.net/job/Test_openjdk17_hs_sanity.openjdk_arm_linux_testList_2/40/
• test-docker-ubuntu2404-armv7-9 - https://ci.adoptium.net/job/Test_openjdk17_hs_sanity.openjdk_arm_linux_testList_2/38/
• test-docker-ubuntu2404-armv7-9 - https://ci.adoptium.net/job/Test_openjdk17_hs_sanity.openjdk_arm_linux_testList_1/70/
• test-docker-ubuntu2404-armv7-1 - https://ci.adoptium.net/job/Test_openjdk17_hs_sanity.openjdk_arm_linux_testList_1/70/

So I'm excluding this test from arm32 on jdk8 and jdk11 only (no arm32 builds for jdk21+).
