Java material – strange exception

I use substance look and feel version 6.0 in Java Swing applications This application applies to me, but some application users, especially those using Windows 7, are getting material exceptions:

java.lang.InternalError: Unable to instantiate org.pushingpixels.substance.internal.contrib.randelshofer.quaqua.colorchooser.ColorPalettesChooser

This exception occurs on the last line of this Code:

JXColorSelectionButton myColorSelectionButton = new JXColorSelectionButton();

myColorSelectionButton.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));
myColorSelectionButton.setFocusPainted(false);
contentPane.add(myColorSelectionButton,cc.xy(29,19));
/**
  * Some code here
  */
myColorSelectionButton.setBackground( Color.WHITE );  // Excepton occurres here !!

I can't find a place to ask this material question, so I would appreciate it if you could help me

Solution

The immateriality of the current build (this is the maintenance branch of matter) and swing x will not have this error, so it is a fixed error

This is a code example

import java.awt.Color
import javax.swing.*
import org.jdesktop.swingx.JXColorSelectionButton

SwingUtilities.invokeAndWait {
@Grapes( 
[@Grab(group='org.swinglabs',module='swingx-core',version='1.6.2-2'),@Grab(group='com.github.insubstantial',module='substance-swingx',version='7.0') ]
)
    JFrame frame = new JFrame("Test");
    JXColorSelectionButton myColorSelectionButton = new JXColorSelectionButton();

    myColorSelectionButton.setFocusPainted(false);
    frame.add(myColorSelectionButton);
    myColorSelectionButton.setBackground( Color.WHITE );  // Excepton occurres here !!
    frame.pack()
    frame.setVisible(true)
}
