Just wanted to say I fixed the problem myself. It seems in my infinite
genius I had the JList added to 2 different JScrollPanes and not only that,
but I was adding the JList itself (and not even either one of the
scrollPanes) to the JPanel. I removed a scrollpane (obviously unneeded) and
modified the JPanel add method's argument to be the leftover scrollpane and
not the JList and now the JList doesn't shift in size.

thanks for your help Pete.
