JDBC database connections using a driver earlier than 126.96.36.199 fail with a "Socket read timed out" error, such as the one listed in the following exception stack:
org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is java.sql.SQLException: Exception occurred while getting connection: oracle.ucp.UniversalConnectionPoolException: Cannot get Connection from Datasource: java.sql.SQLRecoverableException: IO Error: Socket read timed out

With a high number of JDBC connections, the "IO Error: Socket read timed out" error occurs.
