Bug 119827 Window working set has strange name in type hierarchy view
Build id: I20051206-1200 Don't know if this is JDT/UI or Platform/UI but when the window working set is selected a strange name is presented in the title bar of the view (see attached screen shot)
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/callhierarchy/SearchUtil.java
if (workingSet != null) {
					foundLRU= true;
					SearchUtil.fgLRUWorkingSets.add(new IWorkingSet[]{workingSet});
				}
			}
		}
		if (foundLRU)
			
			saveState();
	}
	
	public static String toString(IWorkingSet[] workingSets) {
		Arrays.sort(workingSets, new WorkingSetComparator());
		String result= ""; 
		if (workingSets != null && workingSets.length > 0) {
			boolean firstFound= false;
			for (int i= 0; i < workingSets.length; i++) {
				String workingSetName= workingSets[i].getName();
				if (firstFound)
					result= Messages.format(CallHierarchyMessages.SearchUtil_workingSetConcatenation, new String[] {result, workingSetName}); 
				else {
					result= workingSetName;
					firstFound= true;
				}
			}
		}
		return result;
	}
