Lines 19 to 32 in 40d1479

	private static volatile EmulateResponseManager client;
	private int fakeErrorCount = 0;
	public static EmulateResponseManager getInstance() {
	if (client == null) {
	synchronized (EmulateResponseManager.class) {
	if (client == null) {
	client = new EmulateResponseManager();
	}
	}
	}
	return client;
	}

Can be easily replaced with simpler and faster

    private static final EmulateResponseManager client = new EmulateResponseManager();

    private int fakeErrorCount = 0;

    public static EmulateResponseManager getInstance() {
        return client;
    }
