[deltaspike] restricting the amount of windows

with codi it was possible to restrict the number of windows and old windows are dropped if the maximum was reached and a new window should get created.
deltaspike doesn't allow that before v1.1.0, however, it's very easy to implement it manually:

	@SessionScoped
	@JsfPhaseListener
	public class WindowQuotaHandler implements PhaseListener
	{
	@Inject
	private WindowContext windowContext;
	private Stack<String> windowIdStack = new Stack<String>();
	@Override
	public synchronized /*no issue due to session-scoped instance*/
	void afterPhase(PhaseEvent event)
	{
	String currentWindowId = windowContext.getCurrentWindowId();
	if (currentWindowId == null)
	{
	return;
	}
	if (windowIdStack.contains(currentWindowId))
	{
	windowIdStack.remove(currentWindowId);
	windowIdStack.push(currentWindowId);
	}
	else
	{
	windowIdStack.push(currentWindowId);
	if (windowIdStack.size() > 30) //restricted to 30 windows
	{
	String windowIdToRemove = windowIdStack.remove(0);
	windowContext.closeWindow(windowIdToRemove);
	}
	}
	}
	@Override
	public void beforePhase(PhaseEvent event)
	{
	}
	@Override
	public PhaseId getPhaseId()
	{
	return PhaseId.RENDER_RESPONSE;
	}
	}
