Experiencing an issue with ScheduledExecutorService alongside VT

[Yuval Lombard]

Hi Team,

For the sake of accuracy and integrity, I have noticed the previous thread
dump was taken from a piece of code that does not match the provided
example I attached in the first couple of mails I have sent.
I have attached a new thread dump file that was taken from the exact
version of the code I was testing.

Will appreciate it if you could take a look again just to make sure you see
the issue ( related to preemption when cancelling a timer after
Object.wait(millis) ) you found in the previous dump I attached.

Apologies
