Bug 5474 should not use tool tips for labels
To be consistent with other preference pages, the debug preference labels for step filtering (filter sythetic methods, etc), should not specify tool tips. Instead, the relevant information should just be in the label.
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/preferences/JavaDebugPreferencePage.java
String message= "Could not open package selection dialog for step filters";
			ExceptionHandler.handle(jme, title, message);
			return;			
		}
	
		dialog.setTitle("Add package to step filters");
		dialog.setMessage("Select a package to filter when stepping");
		if (dialog.open() == IDialogConstants.CANCEL_ID) {
			return;
		}
		
		Object[] packages= dialog.getResult();
		if (packages != null && packages.length > 0) {
			IJavaElement pkg = (IJavaElement)packages[0];
			String filter = pkg.getElementName();
			if (filter.length() < 1) {
				filter = "(default package)";
			} else {
				filter += ".*"; 
			}
			fStepFilterContentProvider.addFilter(filter, true);
		}		
	}
	private void removeFilters() {
		IStructuredSelection selection = (IStructuredSelection)fFilterViewer.getSelection();		
		fStepFilterContentProvider.removeFilters(selection.toArray());
	}
