Bug 8142 no scoped type hierarchy on binary projects
When I hit F4 on a binary project selection (e.g. org.apache.ant), I get: 'No declaration of selected members in the chosen hierarchy of 'org.apache.ant'. I would expect to see the class hierarchies of the internal jars. BTW, what does the message mean? I don't understand it.
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/typehierarchy/TypeHierarchyLifeCycle.java
private List fChangeListeners;
	
	public TypeHierarchyLifeCycle() {
		this(false);
	}	
	
	public TypeHierarchyLifeCycle(boolean isSuperTypesOnly) {
		fHierarchy= null;
		fInputElement= null;
		fIsSuperTypesOnly= isSuperTypesOnly;
		fChangeListeners= new ArrayList(2);
	}
	
	public ITypeHierarchy getHierarchy() {
		return fHierarchy;
	}
	
	public IJavaElement getInputElement() {
		return fInputElement;
	}
	
	
	public void freeHierarchy() {
		if (fHierarchy != null) {
			fHierarchy.removeTypeHierarchyChangedListener(this);
			JavaCore.removeElementChangedListener(this);
			fHierarchy= null;
			fInputElement= null;
		}
