Step 5 states, "Version 1.5.0 will automatically become the default Java platform on Solaris 9 or 10..." Version 1.4.2 is currently the default Java for Solaris 9. (To be specific, it is one of the 1.4.2_0x updates, but I'm not sure which.) This will change when S9 is updated to the JDS, but as of now, tiger is not the default.

This also shows the wrong default Java for Solaris 9.
