Thomas,
It doesn't seem to work. For completeness:
- I'm using the current trunc, so I changed the code of
AbstractJSVGComponent, not JSVGComponent.
After running the changed code I've added some extra System.out statements
in AbstractJGVTComponent to show some of the program flow. Every time
needRender is changed or used I logged it to the console. I also generated a
stacktrace when the rendering was halted. Together with the log4j statements
in my app I got the trace below. Hope it helps.
