Bug 27455 [JFace] Hyperlink colors all black
PDE editors use platform UI settings for hyperlink colors. Since driver 1127 (or maybe driver or two earlier, but this is where we noticed it), these colors are all black. The actual colors shown in the preference page are correct (dark blue and blue for standard and active hyperlink colors), but the actual Color object we get from JFace colors has RGB 0,0,0.

/**
 * This class represents the TOP of the workbench UI world
 * A plugin class is effectively an application wrapper
 * for a plugin & its classes. This class should be thought
 * of as the workbench UI's application class.
 *
 * This class is responsible for tracking various registries
 * font, preference, graphics, dialog store.
 *
 * This class is explicitly referenced by the 
 * workbench plugin's  "plugin.xml" and places it
 * into the UI start extension point of the main
 * overall application harness
 *
 * When is this class started?
 *      When the Application
 *      calls createExecutableExtension to create an executable
 *      instance of our workbench class.
