Is it possible to handle alerts using PhantomJS driver with Arquillian Graphene?

I'm using this code:

driver.switchTo().alert();

but I get the following error:

org.openqa.selenium.UnsupportedCommandException: Invalid Command Method - Request => {"headers":{"Accept":"application/json, image/png","Cache-Control":"no-cache","Connection":"Keep-Alive","Host":"localhost:13154"},"httpVersion":"1.1","method":"GET","url":"/alert_text","urlParsed":{"anchor":"","query":"","file":"alert_text","directory":"/","path":"/alert_text","relative":"/alert_text","port":"","host":"","password":"","user":"","userInfo":"","authority":"","protocol":"","source":"/alert_text","queryKey":{},"chunks":["alert_text"]},"urlOriginal":"/session/efc65b30-877e-11e3-ae1b-d71dcb81b53f/alert_text"}
