Bug 44891 Search view hanging while resorting search matches
Build 3.0 M4 Search all references to type String in self-hosted workspace. Finds almost 80.000 of them. Now sort them by parent name... it will take minutes to recover, while it works UI is entirely non responsive.

private ILabelProvider fLabelProvider;
	/*
	 * Overrides method from ViewerSorter
	 */
	public int compare(Viewer viewer, Object e1, Object e2) {
		String name1= null;
		String name2= null;
		if (e1 instanceof ISearchResultViewEntry)
			name1= fLabelProvider.getText(e1);
