Bug 4166 DCR: Javadoc for implementers of a method (1GJJ5LD)
If I hover over a method which implements an interface or overrides a method I would like to see the corresponding Javadoc (unless I also added my own Javadoc). NOTES:
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/util/JavaUIHelp.java
private IJavaElement fElement;
		private IHelpResource[] fHelpResources;
		private IContext fContext;
		private String fText;
		public JavaUIContext(IContext context, IJavaElement element) {
			Assert.isNotNull(element);
			Assert.isNotNull(context);
			fElement= element;
			List helpResources= new ArrayList();
			fContext= context;
			IHelpResource[] resources= context.getRelatedTopics();
			if (resources != null) {
				for (int j= 0; j < resources.length; j++) {
					helpResources.add(resources[j]);
				}
			}
			try {
				URL url= JavaDocLocations.getJavaDocLocation(fElement, true);
				if (url == null || doesNotExist(url)) {
					if (fElement.getElementType() != IJavaElement.JAVA_PROJECT) {
						
						IPackageFragmentRoot root= JavaModelUtil.getPackageFragmentRoot(fElement);
						if (root != null)
							if (root.getKind() == IPackageFragmentRoot.K_BINARY) {
								url= JavaDocLocations.getJavaDocLocation(root, true);
								element= root;
							} else if (root.getKind() == IPackageFragmentRoot.K_SOURCE) {
								url= JavaDocLocations.getJavaDocLocation(root.getJavaProject(), true);
								element= root.getJavaProject();
