Bug 71283 Type Hierarchy View should show active working set in content description [type hierarchy]
Eclipse 3.0 The type hierarchy should show the active working set in the content description. Instead of WorkbenchPart#setTitle(), it should use setContentDescription() to display the focus type and active working set.
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/typehierarchy/TypeHierarchyViewPart.java
updateTitle();

				} else if (fSelectedType != null) {
					
					internalSelectType(fSelectedType, true);
					updateMethodViewer(fSelectedType);
				}
			} else {
				methodSelectionChanged(fMethodsViewer.getSelection());
