Thanks all your guys' help!
Finally I dig it out: in MediaTracker.addImage(Image, int), I add a constant 0
as image ID, and waitForID(0) every time.
Somehow, JVM messed up there and can't release the resources even I request
Image.flush().
Now I change it to addImage(image, m_counter), and waitForID(m_counter), plus
that Image.flush(). JVM release graphics resources now.

It is not surprising that after you call addImage() it will add
that image onto the component without removing others. To my
understanding addImage means you add the image to a list of
the images the compnent holds. Therefore the component still keeps
the references to other images you no longer need after you add a
new image into it. You need to remove the images from that list
to save memory.
As for me, I would use a single Image object and dynamically change the
Graphics object associated wi
