Address a couple nullness errors.
One is from cl/725859649 (I thought I had tested that change with nullness checking on), and the other is from a change to the annotations for
Map.replace
used by Android. (I think that the latter change should actually be leading to more errors in our other implementations of the 3-argMap.replace
, like inMaps
andSynchronized
. The lack of errors is probably a bug in the checker.)RELNOTES=n/a
