The conformance tests validating the GetThreadCpuTime and GetThreadUserTime fails when run with
Specific VM options: "-XX:+UnlockExperimentalVMOptions -XX:-VMContinuations"

As per the spec - "If the thread of the specified ID is a virtual thread thease methods supposed to return -1."
The tests works fine in general, but fails when run with "-XX:+UnlockExperimentalVMOptions -XX:-VMContinuations"

Attached the code snipped to demonstrate the issue.
