> JDBC Autoscaler event handler doesn't allow the event message is null, but
> the message may be null when we handle the exception.
> We consider the exception message as the event message, but the exception
> message may be null, such as: TimeoutException. (It has been shown in
> following picture.)
> Also, recording a event without any message is meaningless. It doesn't have
> any benefit for troubleshooting.
> Solution:
> * Consider the exception message as the event message when exception message
> isn't null
> * The whole Exception as the event message if exception message is null.
