com.gargoylesoftware.htmlunit.ScriptException: Exception invoking jsxGet_cookie February 14, 2012

I was running HtmlUnit 2.9 with Google App Engine in development environment, and hit upon this exception when loading a url:

Truncated Exception is pasted below:

com.gargoylesoftware.htmlunit.ScriptException: Exception invoking jsxGet_cookie
 at com.gargoylesoftware.htmlunit.javascript.JavaScriptEngine$HtmlUnitContextAction.run(JavaScriptEngine.java:595)
 at net.sourceforge.htmlunit.corejs.javascript.Context.call(Context.java:537)
 ...
Caused by: java.lang.RuntimeException: Exception invoking jsxGet_cookie
 at net.sourceforge.htmlunit.corejs.javascript.MemberBox.invoke(MemberBox.java:198)
 ... 65 more
Caused by: java.lang.IllegalArgumentException: Invalid port: -1
 at org.apache.http.cookie.CookieOrigin.<init>(CookieOrigin.java:58)
 ... 82 more

This is due to a bug in Google App Engine and following is the workaround to fix it in htmlunit for the time being.

Workaround

webClient.setCookieManager(new CookieManager()
{
protected int getPort(final URL url)
{
final int r = super.getPort(url);
return r != -1 ? r : 80;
}
});

then you need to add an attribute -XX:UseSplitVerifier to your Default VM arguments.

On Eclipse : Windows -> Preferences -> Java -> Installed JRE’s

And selected and edit, the one that you are using, to include -XX:-UseSplitVerifier

Hope that helps
