Bug 58817 UI no longer responsive when sorting search matches
Build 20040413 I searched for references to type: java.lang.System in org.eclipse.jdt.core project. This found over 4000 matches. I attempted to sort them by parent name, and my IDE locked for about 5 minutes to do the work, with no progress indication, no refresh and 100% CPU usage. Clearly something to improve on UI responsiveness front.

fContentProvider.elementsChanged(objects);

	protected void clear() {
		if (fContentProvider != null)
			fContentProvider.clear();
	}
	protected void configureTableViewer(TableViewer viewer) {
		viewer.setUseHashlookup(true);
		viewer.setLabelProvider(new DecoratingLabelProvider(new SortingLabelProvider(this), PlatformUI.getWorkbench().getDecoratorManager().getLabelDecorator()));
		fContentProvider=new JavaSearchTableContentProvider(this);
		viewer.setContentProvider(fContentProvider);
		setSortOrder(fCurrentSortOrder);
	}
	protected void configureTreeViewer(TreeViewer viewer) {
		viewer.setUseHashlookup(true);
		viewer.setSorter(new ViewerSorter());
		viewer.setLabelProvider(new DecoratingLabelProvider(new PostfixLabelProvider(this), PlatformUI.getWorkbench().getDecoratorManager().getLabelDecorator()));
		fContentProvider= new LevelTreeContentProvider(this, fCurrentGrouping);
		viewer.setContentProvider(fContentProvider);
	}
	
	protected TreeViewer createTreeViewer(Composite parent) {
		return new ProblemTreeViewer(parent, SWT.MULTI | SWT.H_SCROLL | SWT.V_SCROLL);
	}
	
	class MyProblemTable extends ProblemTableViewer {
		MyProblemTable(Composite parent, int flags) {
			super(parent, flags);
