Experiencing an issue with ScheduledExecutorService alongside VT

[Yuval Lombard]

Hi Alan,

Thanks for your feedback
Happy to hear that the issue is observed.
Yes, we are currently blocked by Spring's support, so I guess it will take
us some time until we can resume testing
I don't think we will have the privileges of dedicating time to try and
adjust our branch to work with the two EAs.
I am also concerned about possible noise that can come up when testing two
EAs so we will wait
