/**
 * A {@code FrameworkEvent} listener. {@code FrameworkListener} is a listener
 * interface that may be implemented by a bundle developer. When a
 * {@code FrameworkEvent} is fired, it is asynchronously delivered to a
 * {@code FrameworkListener}. The Framework delivers {@code FrameworkEvent}
 * objects to a {@code FrameworkListener} in order and must not concurrently
 * call a {@code FrameworkListener}.
 * 
 * <p>
 * A {@code FrameworkListener} object is registered with the Framework using the
 * {@link BundleContext#addFrameworkListener(FrameworkListener)} method.
 * {@code FrameworkListener} objects are called with a {@code FrameworkEvent}
 * objects when the Framework starts and when asynchronous errors occur.
