Never believe what you read Joe :-)

There is no such thing as a default JDBC driver

That is the JDBC-ODBC driver which was never supported and we removed it from the JDK as it is not supported.  It was never a requirement of Java SE or JDBC to be there.  It predates type 4 JDBC drivers going back to 1996-1997 during the initial prototyping of JDBC (back to my Sybase days).
