By accident I stumbled upon several timeouts in our test history and I can't find any matching bug.
At first inspection this looks like a long running test that runs with Xcomp and TieredStopAtLevel=2.

Closing as dup.

I think this is a duplicate of JDK-8256024.

The test is marked with @requries vm.compiler2.enabled since 2019. It seems to run anyway under some conditions.
Reducing the main loop to 1000 iterations and adding CompileThresholdScaling allows the test to run with C1 only in about 40 seconds.

A quick guess is that this is a testbug - the thread stacks looks like the test is still making progress. And looking at the test - it seems to have a very combinatorial time. Adding threshold scaling and reducing the outer loop will probably make wonders for this test.
