Bug 88724 Provide 'since' javadoc in snippets
It would be a useful additional information in some snippets if there were an @since javadoc tag that tells from which version on the snippet will work. For instance, snippet 175 works only from Eclipse 3.1 on, since it uses the GridData.exclude field which was introduced in 3.1

static int[] data = new int[0];
public static void main (String [] args) {
	final Display display = new Display ();
	Shell shell = new Shell (display);
	shell.setLayout(new FillLayout());
	final Table table = new Table(shell, SWT.BORDER | SWT.VIRTUAL);
	table.addListener(SWT.SetData, new Listener() {
		public void handleEvent(Event e) {
			TableItem item = (TableItem)e.item;
			int index = table.indexOf(item);
			item.setText("Item "+data[index]);
		}
	});
	Thread thread = new Thread() {
		public void run() {
			int count = 0;
			Random random = new Random();
			while (count++ < 500) {
				if (table.isDisposed()) return;
