Status: REOPENED

(Core :: XPConnect, defect)

Description

[Alexei Barantsev]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.4 (KHTML, like Gecko) Chrome/22.0.1229.94 Safari/537.4

Steps to reproduce:

Inspired by Selenium issue 4309 (http://code.google.com/p/selenium/issues/detail?id=4309)

Run the following Selenium script:

WebDriver driver = new FirefoxDriver();
driver.get("http://cheapflights.co.uk");
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
for (int i = 0; i < 20; i++) {
  driver.findElement(By.cssSelector("div.home-link-groups a")).click();
  driver.navigate().back();
}
driver.quit();


Actual results:

Intermittently it fails because browser throws an exception:

Timestamp: 12.10.2012 20:02:10
Error: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [xpcIJSWeakReference.get]"  nsresult: "0x80004005 (NS_ERROR_FAILURE)"  location: "JS frame :: file:///C:/Users/alexei/AppData/Local/Temp/anonymous8072089874289580448webdriver-profile/extensions/[e-mail]/components/session.js :: <TOP_LEVEL> :: line 1453"  data: no]
Источник: file:///C:/Users/alexei/AppData/Local/Temp/anonymous8072089874289580448webdriver-profile/extensions/[e-mail]/components/session.js

Expected results:

According to specification (http://dxr.mozilla.org/mozilla-central/js/xpconnect/idl/xpcIJSWeakReference.idl.html), xpcIJSWeakReference.get should not throw exceptions, it should return null if a weak reference can't be resolved.
