You could do it in the provided code, however keep in mind that the ZK path currently uses it as well and would expect the empty string. The alternative is to do the substitution (`"" -> null`) when creating the `ClientQuotaEntity`, which is exclusive to the `AdminClient` path. Oh wait, there's also other places where the default is used and expected to be the empty string (broker config), so it may be best to only make the change at the `ClientQuotaEntity`. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
