testlibrary_tests/ir_framework/tests/TestCompileThreshold.java fails intermittently with the following message:
"Caused by: compiler.lib.ir_framework.shared.TestRunException: public void ir_framework.tests.TestCompileThreshold.testWithCompileThreshold() should have been compiled" on aarch64. The failure has been observed in multiple, unrelated personal JDK builds but not on mainline CI's builds yet. It seems to trigger more often on macosx-aarch64-debug than on linux-aarch64-debug.

It can be e.g. reproduced on top of the JEP 475 implementation (commit 47c982ba in https://github.com/robcasloz/jdk/tree/JDK-8334060-g1-late-barrier-expansion) with an approximate failure rate of 10-15% on macosx-aarch64-debug.
