<Swing Dev> How to search for a JRE 7 Mac Bug?

[Jeff Martin]

Thanks! I filed the bug but it isn't available quite yet: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7193703

My situation is probably unique because my JProgressBar sometimes doesn't get shown onscreen. I found a work around though, which is to call updateUI() on it after setIndeterminate(true) - this stops the timer plus InvocationEvents. I've attached my sample code below.
