> While investigating some odd jenkins failures from 
> TriggerSetPropertiesIntegrationTest, I'm left with the conclusion that as 
> implemented, the test was susceptible to order of operation bugs due to how 
> the multiple threads would access a static _non-final *non-volatile*_ 
> CountdownLatch for keeping track of when/if anough iterations had past -- 
> based on the (limited) logging that was being produced, it seemed like 
> thescheduled threads were picing up the "first" {{new CountdownLatch(1)}} 
> assigned to that variable, even though the test expected it to use the second 
> {{new CountdownLatch(2)}}
> It's possible that just marking this variable {{volatile}} would have 
> prevented these failures -- but as designed the test was also very dependent 
> on arbitrary {{sleep()}} delays, so instead i've redisgned it to use 
> differnet signaling mechanisms using {{await()}} calls on concurrent signal 
> structures.
> Opening this issue to track these test improvements and any subsequent tweaks 
> needed
