Try something like:
import org.apache.batik.bridge.UpdateManager;
import org.apache.batik.util.RunnableQueue;
[...]
JSVGCanvas svg; // Your SVG Canvas.
UpdateManager um = svg.getUpdateManager()
RunnableQueue rq = um.getUpdateRunnableQueue();
rq.invokeLater(new Runnable() {
public void run() {
// Code that modifies the DOM tree...
}
});
I suspect (& hope) that this will solve many of your problems...
