Test jobs not completing on test-macstadium-macos11-arm64-2 with ChannelClosedException

[smlambert]

Raising this to monitor it, in case it starts being a recurring problem.

Recent occurrences of test jobs failing with ChannelClosedException:

To make it easy for the infrastructure team to repeat and diagnose, please answer the following questions:

• test suite/name (e.g, BUILD_LIST, TARGET, CUSTOM_TARGET)? not specific to test suite
• a link into recent Test_ job on https://ci.adoptium.net which showed the failure
  • https://ci.adoptium.net/job/Test_openjdk11_hs_extended.system_aarch64_mac/111
  • https://ci.adoptium.net/job/Test_openjdk11_hs_sanity.openjdk_aarch64_mac/112/
• Hyperlink to re-run in Grinder:
• Is there an existing issue elsewhere covering this?
• Which machine(s) does it work on?
• Which machine(s) does it fail on? test-macstadium-macos11-arm64-2

Any other details: Maybe this is a two-off failure from the recent jdk11 2282 build pipeline, will keep monitoring to see if it recurs: https://trss.adoptium.net/searchResult?buildId=63fe453317052c6715e8d8ee&searchText=ChannelClosedException
