Andrew Purtell commented on HBASE-19379:
----------------------------------------
This stems from a change I made to fix an error-prone warning.
Before we were doing {{selectedLoc == thisLoc}} in RegionLocations. I changed
that to {{Objects.equals(selectedLoc, thisLoc)}} and so
HRegionLocation#compareTo now has to handle the case where what it's testing is
{{null}}. This is a trivial change. I will commit the fix momentarily to
branch-1.4 and branch-1.
Let me also check if the failure [~stack] mentioned with TestGlobalThrottler is
related.
