Oleg Zhurakousky commented on NIFI-1164:
----------------------------------------
While patch is submitted it does not really provide a fix. Rather decreases the
chances for this bug to manifest itself the way it did before. At the core if
the issue in both NIFI-1143 and this one is the fact that the service state
checks are somewhat pointless since the actual service state may (and does in
this case) change rendering the next action invalid.
Will raise another JIRA for 0.5+ to fix it properly
> Race condition during initialization of ControllerServices - (part due)
