Berenguer Blasi commented on CASSANDRA-16587:
---------------------------------------------
Been thinking a bit more...
For the byteman problem we could use a server socket in some weird port number
rather than a file as the file may/usually survives jvm and other crashes. I
would expect the server socket to die if the jvm goes down on the other hand
iirc. That would make it deterministic indeed as you point out.
But for other tests having a deterministic behavior is not easy imo. We can't
detect if some other test not using the rule is changing or using shared ips
under our feet. The problem here is that if 'fails silently' and these can be
hellish flakies.
