7.9.8 (b2018053113)
Oracle Corporation 1.8.0_171

Are you using the newest version of the connector?

Yes, I believe this is the newest version.

This is the message in details-

Databases / Connection [MySQL]

Cannot create PoolableConnectionFactory (java.lang.ClassCastException: java.math.BigInteger cannot be cast to java.lang.Long)

And he connector- mysql-connector-java-5.1.23-bin.jar

Which version of MySQL Server are you trying to connect to?

Its version 8.0.11. Also, I’m using Mac if that creates any difference. Thanks

You’ll need an updated JDBC driver and some extra connection properties:

Hi Kevin, thanks for the suggestion. But I am still not able to connect the database.

uninstall version 8.0.1 completely and delete any left over files and folders. Install 5.7.x. It will work perfectly.
