Thierry,
I ran the sequence again and set the
JSVGCanvas.setDocumentState(JSVGComponent.ALWAYS_DYNAMIC). I didn't notice
any difference. Here is my backtrace. I don't know that the percentage
numbers are apples to apples since the total memory usage was different this
time. However I did observe the same increase of the int[] arrays on each
subsequent rendering of the image.
