In the SapMachine CI we see the test runtime/ErrorHandling/MachCodeFramesInErrorFile.java reproducibly failing since several weeks now.
A jtr log excerpt contains this:
java.lang.RuntimeException: 1 < 2
at jdk.test.lib.Asserts.fail(Asserts.java:594)
at MachCodeFramesInErrorFile.run(MachCodeFramesInErrorFile.java:169)
at MachCodeFramesInErrorFile.main(MachCodeFramesInErrorFile.java:107)
at java.base/jdk.internal.reflect.DirectMethodHandleAccessor.invoke(DirectMethodHandleAccessor.java:103)

at java.base/java.lang.Thread.run(Thread.java:1570)

Maybe it is related to JDK-8275677, but the error does not look exactly the same, so I open a new bug for this issue.
