Doc from com.mysql.cj.jdbc.ha.LoadBalanceExceptionChecker.shouldExceptionTriggerFailover.

Invoked to determine whether or a given SQLException should trigger a failover in a load-balanced deployment. The driver will not pass in a Connection instance when calling init(), but it will pass in the Properties, otherwise it acts like a normal Extension. One instance of a handler *per* JDBC connection instance will be created. If you need singleton-like behavior, you're on your own to provide it.

Parameters
ex:Throwable

exception

Returns:boolean

true if the exception should trigger failover.
