This test failed once for me with -Xcomp -XX:CompileThreshold=100 -XX:+UnlockExperimentalVMOptions -server -XX:+TieredCompilation -XX:+DeoptimizeALot. The output is

If I read the test output correctly, it has printed the stack trace of the carrier thread (not the virtual thread). It is possible that calling GetStackTrace during a transition will return the stack trace of the carrier?
