Sorry, I’ve been a little busy lately.
I had a look, and yes it seems there’s a bug there. I wasn’t able to
reproduce it with the test file you gave, though. I’ve committed a
change: please let me know if it fixes your problem.
Thanks,
Cameron

I’ve (finally) commited this fix to SVN.

After stress testing we discovered that there is a performance issue wrt
to Overlays. our app implements the Overlay interface, to permit users
to draw strokes on the canvas. When strokes are made with the mouse, all
is fine, but if strokes are made with the pen from a tablet PC, there is
significantly more lag. Could this be related in some way to the problem
we were addressing?

Cameron,
I applied the fix you suggested and it worked. I have to do some stress
testing now to make sure but all seems well. I'll let you know if I find
anything, but in the mean time, I would recommend making this fix
permanent. Thanks again for your help!

Sorry I’m away at the moment and probably won’t get a chance to look at
it for a couple of weeks. After a *brief* look, it may be that that
AnimationEngine.java:347 line,
if (sandwich.shouldUpdate || sandwich.animation.isDirty) {
just needs a guard against the NPE with
if (sandwich.shouldUpdate ||
sandwich.animation != null && sandwich.animation.isDirty) {
but I’ll have to investigate more deeply that there isn’t a deeper bug
causing the problem.
Thanks,
Cameron

Hi Cameron,
Were you able to have a second look at this? Please let me know if you
need anything from me. I'm eager to help getting this resolved. Thanks.

A little info which might be helpful:
1) Using a plain canvas, I scribbled, then went to another plain canvas,
no problem (forward movement seems to work ok). (slide1.svg)
2) I then revisited the slide. Still no problem. (slide1.svg)
3) The second I start to scribble on that slide, those NPEs come rolling
across the console. The saved slide is slide3.svg
Let me know if you need more info. Thanks.

Rats!! Pre-mature rejoicing is never a good thing. Sorry. I was able to
get past navigating the first slides, then I revisited the slides and
saw a repeat of the symptoms. Here's the exception:
java.lang.NullPointerException
at
org.apache.batik.anim.AnimationEngine.tick(AnimationEngine.java:347)
at
org.apache.batik.bridge.SVGAnimationEngine.access$600(SVGAnimationEngine.java:98)
at
org.apache.batik.bridge.SVGAnimationEngine$AnimationTickRunnable.run(SVGAnimationEngine.java:844)
at org.apache.batik.util.RunnableQueue.run(RunnableQueue.java:237)
at java.lang.Thread.run(Thread.java:595)
Once again, this seems to repeat endlessly until I end the session (I
didn't try to see if it ended when I scribbled). I tried Attaching the
documents before and after I noticed the first delay but the mail server
refused. These slides both had images
to begin with. Is there somewhere I can send these that won't reject
them? Thanks.
I will do some more testing in the mean time to see if I uncover
anything new.
