Your error clearly says casting is not possible, because a java.math.BigInteger class instance is not an instance of java.lang.Long class.
Now the question arises who is doing casting at what level, when we ask the JDBC driver to make a connection, it is doing lot of work behind the scene before it actually give us back the proper working object of connection.
The problem seems with your version of MySQL in combination with your version of mysql-connector.jar. Try a newer version of MySQL Connector/J (see https://dev.mysql.com/downloads/connector/j/ for the latest version), for example upgrade to 5.1.47 or 8.0.12 if you are using an older version.
