> When the bookie shuts down due to some exception, it exits with exitCode 0.
> We try to get the exitCode when calling System.exit() here:
> https://github.com/apache/bookkeeper/blob/master/bookkeeper-server/src/main/java/org/apache/bookkeeper/proto/BookieServer.java#L400
> But the exitCode is set by the shutdown hook which is triggered by
> System.exit(). Thus, we will always exit with code 0.
> Solution:
> We explicitly call bookie shutdown to set the exit code.
