[classlib][swing] JColorChooser.showDialog() throws NPE if JDialog.setDefaultLookAndFeelDecorated(true)
was called
------------------------------------------------------------------------------------------------------------------

                 Key: HARMONY-3016
                 URL: https://issues.apache.org/jira/browse/HARMONY-3016
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
         Environment: WinXP
            Reporter: Vasily Zakharov


Here's the code to reproduce:

import java.awt.Color;
import javax.swing.JColorChooser;
import javax.swing.JDialog;

public class Test {
    public static void main(String[] args) {
        JDialog.setDefaultLookAndFeelDecorated(true);
        JColorChooser.showDialog(null, "JColorChooser", Color.BLACK);
    }
}

It works fine on RI, but causes the following exception on Harmony:

Exception in thread "main" java.lang.NullPointerException
        at javax.swing.plaf.basic.BasicInternalFrameTitlePane.<init>(BasicInternalFrameTitlePane.java:423)

        at Test.main(Test.java:9)

If JDialog.setDefaultLookAndFeelDecorated(true) call is commented, or "true" is replaced with
"false", the window opens normally on both Harmony and RI.

The problem is actual as of r497095.
