<Swing Dev> Bug 6306075

Hi Paulo,

>             JProgressBar old = view.progressBar;
>             view.progressBar = new JProgressBar(current, size);
>             l.replace(old, view.progressBar);

The described bug 
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6306075 is fixed. Is 
the problem reproducible on some jdk?
