Thanks Rolf, believe me I have been trying to solve it myself (62
hours in the last week and counting :-( That's the gist of my plea to
at least release the source so that we can support ourselves.
disposeQTObject is our usual tactic, but right now that blows up our
VM on Mac. We've resorted to a queued disposer, where we wait 10s
after we've finished with any QTObject's before actually disposing of
them, with the termination lock taken around batches (a Movie and its
MovieController), and still I can't click-play more than 200 times
without crashing, usually somewhere in QuickDraw - RegnRect or
something like that.
I think we're going to have to give up on the callbacks altogether
and just observe changes with a Swing Timer, that is, if we don't
give up on QTJ altogether.
We must do that lunch

I _think_ that this is new on 7.2 on Mac, as our app now leaks big-
time - difficult to install old versions of QT to find out though.
The leak manifests itself as ~1MB leak of process memory per play-
new-clip in our app on 7.2. I'm having difficulty persuading QA
that we can release it in this state.

I don't know the specifics of your case as I don't use the
quicktime.app.time.Timer class. It's certainly possible this is a
new bug. Don't be afraid to try and solve it yourself though, using
a decompiler, memory profiler, etc.
I've certainly had to do things like call setMovie(null) or
disposeQTObject() myself before now to fix what I would class as
bugs in QTJava, but that's always been the case if you want a fix
quickly, even back in the days when Bill Stewart was actively
working on it.
You might also consider using the underlying QTCallbacks directly
rather than going through the higher level app class, as that might
give you a bit of extra control over what's going on.
