First, is there a good description available on how the sun.java2d.Disposer

There isn't such a description. Disoser is an internal mechanism
for disposing of graphics-related resources

Hi Dmitri,
Is Mustang b89 recent enough to test?
Yes, that should do it.
Out of curiosity, what was changed wrt the Disposer in Mustang? Is the
disposer thread initialized on JVM startup?
The change is
Could you try the workaround I've suggested?
(do some java2d activity - in particular, create a BufferedImage and
render to it - on a thread created either
prior to creating and setting the InheritableThreadLocalStorage

I'll think on what we can do

Sure, let's say I manageg to remove all the inheritableThreadLocals.
The next issue is the contextClassLoader that is propagated to the Java2D

But before I start asking I need to understand
more about this.
Do you set your own classloader, or is it the default
one?
Better yet, is there any way you could create a small
test case illustrating the problem?
Thanks,

Hi there,
Stupid question time. :-)
Not so stupid, actually. This is because of our bug, which I happy
to report was fixed in mustang.
To work around it, don't use Canvas, just create the BufferStrategy
off your frame.
Also, you might want to use Frame instead of JFrame - you
Well, if he were to just change JFrame to Frame (no
lightweight/heavyweight issues), it still wouldn't work because of
the (fullscreen/BufferStrategy-related) bug. But anyway, the
workaround is indeed to ditch Canvas.

Hello,
what JDK release is this with?
Have you tried JDK6? There were some issues with VolatileImage
initial validation in JDK5, most of which should be
resolved in JDK6.
I'm assuming this is on Windows, correct?
Also, is this with full-screen mode or windowed?
Do you use
Well, it looks like Chet answered your question.
Note that the demo you pointed at to doesn't use
VolatileImages at all.
A couple of suggestions: you might want to refrain from
using Image.getSubImage() method call as it disables
potential use of hardware acceleration for the

this indeed looks like a bug - there's even a comment
in the code to this effect (that it wouldn't work
for non-writable rasters)..
Thanks,
