@nkalmar the
[TxnLogToolkit](https://github.com/apache/zookeeper/blob/master/src/java/main/org/apache/zookeeper/server/persistence/TxnLogToolkit.java)
also has some hard-coded exit code, if we're moving all the exit code
including the ones in the tools into the enum, then we may need to change this
as well.---
