 * <code>FrameworkEvent</code> objects to a <code>FrameworkListener</code>
 * in order and must not concurrently call a <code>FrameworkListener</code>.
 * 
 * <p>
 * A <code>FrameworkListener</code> object is registered with the Framework
 * using the {@link BundleContext#addFrameworkListener} method.
 * <code>FrameworkListener</code> objects are called with a
 * <code>FrameworkEvent</code> objects when the Framework starts and when
 * asynchronous errors occur.
