I would _like_ to use JFileChooser...  but the JList problem simply makes
this useless indeed atm. (For testing, just try to open the last file in
a directory with more than a few dozen files).

Over the weekend, I finally tried to track down and isolate the scrolling 
bugs that make my test application (JImageViewer) unuseable with current 
classpath cvs due to excessive flickering. I strongly suspected JScrollPane 
and friends, but several hours of testing revealed that JScrollPane with
JViewport and Scrollable finally work more or less as they should - at least 
for my testcases. (There remains a clipRect issue, but different versions 
of the JDK disagree on that one, too.) The flickering turned out to be due
to JTree requesting useless revalidates (with wrong sizes). I have not
submitted a bug report for that yet because using JTree in a JScrollPane
is completely broken anyway, and we already have a bug for it. Bug 24145 
is claimed to be invalid, but should be revisited.

IMO, Fixing the Scrollable behaviour of JList and Jtree would make a 
big step towards real-world-application-compatibility of Free Swing.
