Guerry:

I'd look at JProbe from KL.

There are places deep in JFC that hold references.  You can't get to
those, so it's going to leak.  There are some interesting reports in
the BugParade that have some workarounds and explanations.  You might
want to see of those match.

Much of this is being addressed in 1.2.  Of course, this means
deciding if the known bugs in JFC 1.03 and 1.1.6 are better then the
unknown bugs in JDK 1.2 (plus the hassles with moving from "old" JFC
to "new" JFC.
