Tim Onyschak commented on IGNITE-7090:
--------------------------------------
[~vladisav], it looks like when failoverSafe flag is set to false it does not
expect the permits to be given back. i added a failoverSafe check to fix the
test, but i am not sure if thats expected functionality. If yes, code is
checked in.
If we expect the permit to be given back on even in failoverSafe set to false,
we may need to update test. I did not want to change any test until i fully
understood the requirements on that.
I've kicked off a RunAll on team city, let me know what you think.
