Comments
I'm closing this a dup of JDK-8316682 as it is a self-suspend related issue. This intermittent failure is hard to reproduce. Also, all the mach5 links in the comments can not be resolved anymore to get the tested threads stack traces. So, it is not easy to prove this is a dup of JDK-8316682. Please, re-open the bug if this deadlock is still observable.
