Running tier1 on macOS/AArch64 looks good:

TEST FAILURE


Those 6 failures in `jdk:tier` also happen on Linux/AArch64, so I'll ignore them. The hotspot failure happens on `test/hotspot/jtreg/runtime/ErrorHandling/TestOnError.java` with the following output:


TEST RESULT: Failed. Execution failed: `main' threw exception: java.lang.RuntimeException: '^Test Succeeded' missing from stdout


Not sure what's going on.

Circeling back to the r18 issue mentioned here: https://github.com/openjdk/jdk11u-dev/pull/301#issuecomment-911998917
My understanding is that the current stable release of macOS (12.1 Monterey) should already be affected by this issue, as I haven't backported https://bugs.openjdk.java.net/browse/JDK-8274795 to jdk11 yet. Do you have some better reproducer other than running Intellij? Apparently none of the tier1 tests seem to trigger it.
