> have you seen this in builds that have https://bugs.openjdk.org/browse/JDK-8349094? I noticed that JDK-8349094 has been merged 3 days ago, but I was observed this failure several times yesterday. And I have check mine personly fork(git@github.com:sendaoYan/jdk-ysd.git jbs8351233 branch) which already have JDK-8349094 fixed but also observed this failure. I will continue observed this failre will be reprodudeable or not.

[~syan], have you seen this in builds that have https://bugs.openjdk.org/browse/JDK-8349094? JDK-8349094 fixes a few different bugs that could have Shenandoah threads prevent the JVM from shutting down.

Fails since JDK-8347804

Maybe we should problemlist this test before the root cause of timed out fixed.
