Answer 1

For me updating the connector wasn't enough, I also had to complete my DriverManager.getConnection() url parameter with all the arguments, even if the error message was not mentionning this issue.

In my case this parameters were needed : "jdbc:mysql://127.0.0.1:3306/database?zeroDateTimeBehavior=convertToNull&serverTimezone=UTC"

Connector : mysql-connector-java-8.0.17.jar mysql version : 8.0.17

Using java on netbeans.
