Та часть, которая кидать исключение так же просто, как это:

public HtmlPage iniciaSesion(String correo, String pass) throws FailingHttpStatusCodeException, MalformedURLException, IOException{ 
     HtmlPage pagActual; 
     HtmlTextInput cajaTexto; 
     HtmlButton boton; 

     pagActual= cliente.getPage("https://accounts.google.com/login?hl=es#identifier"); 

     return pagActual; 

Основная программа просто вызывает этот метод и использует метод .asXml(), но он бросает исключение перед его использованием.

Вам необходимо включить Javascript на своем клиенте. Этот код должен работать:

LogFactory.getFactory().setAttribute("org.apache.commons.logging.Log", "org.apache.commons.logging.impl.NoOpLog"); 

java.util.logging.Logger.getLogger("com.gargoylesoftware").setLevel(Level.OFF); 
java.util.logging.Logger.getLogger("org.apache.commons.httpclient").setLevel(Level.OFF); 

WebClient client = new WebClient(BrowserVersion.CHROME); 
client.getOptions().setJavaScriptEnabled(true); 
client.getOptions().setThrowExceptionOnScriptError(false); 
client.getOptions().setThrowExceptionOnFailingStatusCode(false); 

String url = "https://accounts.google.com/login"; 
final HtmlPage page = client.getPage(url); 

System.out.println(page.asText());
