Bug 65187 [Themes] Cascading*Registry leakage from Colors and Fonts pref page
Small leak on I20040529 For each ColorsAndFontsPreferencePage this is created, the cascading font and color registries are leaked. This is because the superclasses register a runnable with Display#disposeExec
bundles/org.eclipse.jface/src/org/eclipse/jface/resource/FontRegistry.java
* <p>
     * If no appropriate OS-specific resource bundle is found, the
     * process is repeated using the location as the base bundle name.
     * </p>
     * <p>
     * The property file contains entries that look like this:
     * <pre>
     *	textfont.0=MS Sans Serif-regular-10
     *	textfont.1=Times New Roman-regular-10
     *	
     *	titlefont.0=MS Sans Serif-regular-12
     *	titlefont.1=Times New Roman-regular-12
     * </pre>
     * Each entry maps a symbolic font names (the font registry keys) with
     * a "<code>.<it>n</it></code> suffix to standard font names
     * on the right. The suffix indicated order of preference: 
     * "<code>.0</code>" indicates the first choice,
     * "<code>.1</code>" indicates the second choice, and so on.
     * </p>
     * The following example shows how to use the font registry:
     * <pre>
     *	FontRegistry registry = new FontRegistry("com.example.myapp.fonts");
     *  Font font = registry.get("textfont");
     *  control.setFont(font);
     *  ...
     * </pre>
     *
     * @param location the name of the resource bundle
     * @param loader the ClassLoader to use to find the resource bundle
     * @exception MissingResourceException if the resource bundle cannot be found
