[pshipton]

I see two timeouts?
One on rhel8s390x-rt-2 and one on rhel8s390x-svl-rt3-1

@tajila @babsingh do we need to investigate this failure?

[babsingh]

I’m looking into this issue.

[babsingh]

The timeout most likely occurs because JVMTI InterruptThread returns successfully, but the target unmounted virtual thread does not complete the expected wakeup and termination path. The main test thread is blocked in Thread.join(), which indicates the target virtual thread remains alive rather than the test merely missing an interrupt flag. Given the highly intermittent nature of the failure, this issue should be placed in the backlog. If revisited later, the next investigation should focus on possible gaps in the wakeup path for interrupted unmounted virtual threads.
