ScrollToVisible throws an exception in webview on iOS

[ramgokul]

Selenium Version: 2.43.1
Xcode version: 6.3.1
OSX version: 10.10.3

What I am trying to do:

1. Launch iphone 6 simulator
2. Launch UICatalog app
3. Click on the 'left' button
4. Scroll to Web View'. Tap on it
5. Click on the ‘Menu’ button. Many sublinks like Store, Mac, iPhone, Watch…..Support are displayed.
6. Scroll upto the last link (I,e Support) and click on it

Code:
cap = new DesiredCapabilities();
cap.setCapability("deviceName", "iPhone 6”);
cap.setCapability("platformName", "iOS");
cap.setCapability("platformVersion", "8.3");
cap.setCapability("app", appFile.getAbsolutePath());

dr = new IOSDriver(new URL("http://0.0.0.0:4723/wd/hub"), cap);
dr.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
dr.findElementByIosUIAutomation("UIATarget.localTarget().frontMostApp().navigationBar().leftButton()").click();
dr.findElementByIosUIAutomation("UIATarget.localTarget().frontMostApp().mainWindow().tableViews()[0].cells()["Web View"]").click();
dr.findElementByXPath("//UIAButton[@name='Menu']").click();
Thread.sleep(5000);
dr.executeScript("UIATarget.localTarget().frontMostApp().mainWindow().scrollViews()[0].webViews()[0].links()["Support"].scrollToVisible();");

Observation:

I see that the scroll happening successfully upto the ‘Support’ link. However, the script exits at this point with an exception (An error occurred while executing user supplied JavaScript.). What am I doing wrong?
