while i in no way object to a new implementation, I'm not sure that is the
correct solution to the bug described in NIFI-4774[1]. A new implementation
would need to be tested to a degree that a tweak to the existing implementation
would not, and fixing this bug in a timely fashion would seem to be a worthy
goal.
