Description Miloslav Metelka 2014-07-29 08:56:07 UTC 
Although previously we abandoned the idea due to BasicTextUI.paint() being final:

    public final void paint(Graphics g, JComponent c) {
        if ((rootView.getViewCount() > 0) && (rootView.getView(0) != null)) {
            Document doc = editor.getDocument();
            if (doc instanceof AbstractDocument) {
                ((AbstractDocument)doc).readLock();
            }
            try {
                paintSafely(g);
            } finally {
                if (doc instanceof AbstractDocument) {
                    ((AbstractDocument)doc).readUnlock();
                }
            }
        }
    }

I've found that we could possibly override BasicTextUI.update().

versioning diff sidebars requires read-lock when painting, it would help if it had a chance to ask whether to repaint or not: bug 241545

This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue.

Thanks for your cooperation,
