public class IconTableCellRenderer
extends DefaultTableCellRenderer

The package-private class javax.swing.JTable.IconRenderer, which is the default renderer for columns of class Icon and ImageIcon, is known to give rise to a ClassCastException when attempting to render an Icon whose implementation of paintIcon(Component c, Graphics g, int x, int y) requires a cast of its first parameter to a specific subclass of Component. Many icons obtained from standard JDK classes trigger this ClassCastException.

IconTableCellRenderer addresses this issue in the following manner:

First, attempt to paint the Icon to the Graphics context of a BufferedImage with a reference to itself as the Component parameter.
In case of a ClassCastException, the desired class is identified by parsing the exception's message. An attempt is made to instantiate a Component of the desired class and use it as a valid reference.
In case of an InstantiationException, which is thrown if the desired class is abstract, a final attempt is made to draw the icon with a concretized AbstractButton as the Component parameter.
All else failing, the icon is rendered as a crossed rectangle of the same size as the original icon, or the default icon if supplied as a parameter to the constructor.

Constructor Summary
`IconTableCellRenderer()` Constructs an IconTableCellRenderer which will use a crossed rectangle as default icon
`IconTableCellRenderer(Icon defaultIcon)` Constructs an IconTableCellRenderer which will use the supplied default icon, which must be an icon that is capable of being painted to any JComponent.

Method Summary
`private void`	`createIcon(Icon icon, JComponent component)` Paints the icon to a BufferedImage for use as the renderer's Icon.
`private Color`	`getCorrectBackground(JTable table, boolean isSelected)` Obtains the correct background as per the selection status
`Component`	`getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column)` @see DefaultTableCellRenderer#getTableCellRendererComponent(JTable, Object, boolean, boolean, int, int)
`static void`	`setRowHeightsForIcons(JTable table)`
