Bug 284319 Remove empty Activators and replace Activator.ID Strings with dynamic Bundle symbolic name
I have deleted empty Activators and replaced the String literal of ID with FrameworkUtil.getBundle(...class).getSymbolicName().
bundles/org.eclipse.e4.ui.widgets/src/org/eclipse/e4/ui/widgets/Activator.java
package org.eclipse.e4.ui.widgets;
import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;
/**
 * The activator class controls the plug-in life cycle
 */
public class Activator implements BundleActivator {
	
	public static final String PLUGIN_ID = "org.eclipse.e4.ui.widgets";
	
	private static Activator plugin;
