@andymc12 , actually I expected a concern about this, that's why I opened
up a PR instead of committing directly. I'm not sure we want to keep the former
behavior wrt supporting null keys. I don't think entries with null keys were
actually used before, null keys happened to be "supported" because of the
internal implementation detail choice. This said I believe the code that I
fixed is not calling remove(null) on purpose, basically the change here is
exposing a bug that was there before.
@dkulp what's your opinion on this?
