Cleanup of backpatch of jdbc2 improvements to jdbc1:

Here's what I came up with. The biggest difference api between JDK1.x and
later versions is the support for collections. The problem was with the
Vector class; in jdk1.x there is no method called add, so I changed the
calls to addElement. Also no addAll, so I rewrote the method slightly to not
require addAll. While reviewing this I notices some System.out.println
statements that weren't commented out. So I commented them out in both
versions.

The upshot of all of this is that I have clean compile, but no idea if the
code works ;(
