You have two possible locations to load the libraries from: classes12.jar and ojdbc6.jar. Both of these contain most of the same classes, although implementation may differ between the classes, and you don't know which DriverManager (the one in classes12 or the one in ojdbc6) the JVM is actually using. I would remove one from your classpath and see if it makes a difference.

The Oracle install does include a version of Java that is quite low (I think 1.4).
