This version of Connector J (3.0.13) released May 27 2004 does not accept a database URL that contains a hostname. Eg jdbc:mysql:// 
The error thrown is:
SQLException: java.sql.SQLException: Cannot load connection class because of underlying exception: 'java.lang.NumberFormatException: For input string: ""'.

The same exception is thrown for hostname localhost when used instead of the IP address. Eg jdbc:mysql://localhost/database 

If the database URL completely omits a hostname, the connection succeeds. Eg jdbc:mysql:///database 

This error was tested using Borland JBuilder's Database Pilot and previously functional version of the driver (Version 3.0.11) - when the Driver was replaced with version 3.0.13 the SQLException was thrown.

How to repeat:
The testsuite should have caught this error.
Any functional java program should now fail if the connection URL contains a host name.

Thank you for your bug report. This issue has already been fixed
in the latest released version of that product, which you can download at

The reason the testsuite _did_ not catch this particular bug is because of the number of servers we run it against...They're all on non-standard ports. URL's with port #'s in them worked fine with this release.

This has now been rectified in our testing setup (one server runs on a default port, and the URL does not specify a port).
