Java Substance - Strange exception

Question

I am using Substance look and feel version 6.0 in my Java Swing application. The application works fine for me, but some of the application users especially those using Windows 7 are getting a substance exception :

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

This exception occurs in the last line in 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 Substance question so if you can help me out that would be appreciated.

Answer 1

Substance is no longer updated and is broken on Java 7.

However someone has pick the project back up by forking it and calling it insubstance: http://shemnon.com/speling/

Which it supports Java 7 and seems to have big plans for the next update.

It should be as simple as swapping the libraries over to get it working in your project.

Answer 2

Current builds of insubstantial, (which is a maintenance fork of Substance) and SwingX do not exhibit this error, so it's a bug that has been fixed.

Here's a code sample in

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)
}
