Mark Payne commented on NIFI-4290:
----------------------------------
[~joewitt] - yeah I think there's an easy enough to change - to just
instantiate the object if necessary when calling the getter. We do not create
it when the lease itself is created because it gets 'nulled out' when completed
and then re-created again if anything is sent. However, if we just add the
null-check-and-construct in the getTracker() method I think it addresses the
issue. Will create a PR shortly.
