JDBC 4 shall be backward compatible with JDBC 3 and you shall have no problems replacing the driver.

Quoting from JDBC 4.0 specification 2.2 Overview of goal section, one of the goals of JDBC 4.0 is to

8) Maintain backward compatibility with existing applications and drivers Existing JDBC technology-enabled drivers ( JDBC drivers) and the applications that use them must continue to work in an implementation of the Java virtual machine that supports the JDBC 4.0 API. Applications that use only features defined in earlier releases of the JDBC API will not require changes to continue running. It should be straightforward for existing applications to migrate to JDBC 4.0 technology.
