Known Issues 
The following are known issues that you may encounter due to limitations in the data source the driver or an application.
  • The JDBC 4.0 version of the driver fails to connect to servers that require encryption using TLS 1.1 or later.   When you attempt to connect to the server the connection fails and the driver returns an SSL handshake exception.
