FULL PRODUCT VERSION :
Java(TM) SE Runtime Environment (build 1.7.0_06-ea-b09)

ADDITIONAL OS VERSION INFORMATION :
Mac OS X 10.7.3

A DESCRIPTION OF THE PROBLEM :
For the JProgressBar, there is no animation displayed when setting indeterminate to true. This is 100% consistent, and the animation displays as expected in JDK6 using the same code.

I initially upgraded from JDK6 to the 7u4 release and discovered the bug. I then installed the snapshot release 7u6(b09) and the issue remains.

REGRESSION.  Last worked in version 6u31

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
package progressbartest;

import javax.swing.BoxLayout;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JProgressBar;

public class ProgressBarTest {

    public static void main(String[] args) {
        JFrame mainWindow = new JFrame("Progress Bar Test");
        mainWindow.setSize(480, 320);
        
        JPanel mainPanel = new JPanel();
        mainPanel.setLayout(new BoxLayout(mainPanel, BoxLayout.PAGE_AXIS));
        
        JProgressBar progressBar = new JProgressBar();
        progressBar.setIndeterminate(true);
        progressBar.setString("");
        
        mainPanel.add(progressBar);
        mainWindow.add(mainPanel);
        mainWindow.setVisible(true);
    }
}


REPRODUCIBILITY :
This bug can be reproduced always.
