Java 物质 - 奇怪的异常

Question

我在我的 Java Swing 应用程序中使用 Substance 外观版本 6.0。该应用程序对我来说工作正常，但一些应用程序用户，尤其是那些使用 Windows 7 的用户遇到了实质性异常:

java.lang.InternalError: Unable to instantiate org.pushingpixels.substance.internal.contrib.randelshofer.quaqua.colorchooser.ColorPalettesChooser
at org.pushingpixels.substance.internal.ui.SubstanceColorChooserUI.createDefaultChoosers(SubstanceColorChooserUI.java)

此异常发生在这段代码的最后一行:

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 !!

我找不到问这个 Substance 问题的地方，所以如果你能帮助我，我将不胜感激。

物质不再更新并且在 Java 7 上被破坏。

但是有人通过 fork 并称其为 insubstance 来备份该项目:http://shemnon.com/speling/

它支持 Java 7，并且似乎有下一次更新的宏伟计划。

它应该像交换库一样简单，让它在您的项目中工作。
