OK, I'm trying to "clean" up after I'm done with an SVG document on the
JSVGCanvas:
jsvgCanvas.stopProcessing();
// Done to avoid errors.
Thread.sleep(200);
jsvgCanvas.setDocument(null);
jsvgCanvas.flushImageCache();
At this point, any embedded image files that were being shown on the
JSVGCanvas will not delete. The SVG document itself will delete, but
not the images! How do I get rid of the lock on the image files?
On a related note, when I'm ready to show a new document:
jsvgCanvas.resumeProcessing();
jsvgCanvas.setDocument(...);
...sometimes results in this stack trace:

Any way around that?
This is still the 1/08/2007 SVN build of Batik.
