///**
// * Customizes the starting and stopping of a bundle.
// * <p>
// * <code>BundleActivator</code> is an interface that may be implemented when a
// * bundle is started or stopped. The Framework can create instances of a
// * bundle's <code>BundleActivator</code> as required. If an instance's
// * <code>BundleActivator.start</code> method executes successfully, it is
// * guaranteed that the same instance's <code>BundleActivator.stop</code> method
// * will be called when the bundle is to be stopped. The Framework must not
// * concurrently call a <code>BundleActivator</code> object.
// * <p>
// * <p>
// * <code>BundleActivator</code> is specified through the
// * <code>Bundle-Activator</code> Manifest header. A bundle can only specify a
// * single <code>BundleActivator</code> in the Manifest file. Fragment bundles
// * must not have a <code>BundleActivator</code>. The form of the Manifest header
// * is:
// * <p>
// * <p>
// * <code>Bundle-Activator: <i>class-name</i></code>
// * <p>
// * <p>
// * where <code><i>class-name</i></code> is a fully qualified Java classname.
// * <p>
// * The specified <code>BundleActivator</code> class must have a public
// * constructor that takes no parameters so that a <code>BundleActivator</code>
// * object can be created by <code>Class.newInstance()</code>.
// * <p>
// * remove next version <br>
// *
// * @version $Revision: 6361 $
