New issue 2792 by felixjmo...@gmail.com: Java Heap Space Error when using
Remote Firefox Profile
http://code.google.com/p/selenium/issues/detail?id=2792

I have the following Code:

private static RemoteWebDriver getRemoteFirefox(String host) {
RemoteWebDriver remoteWebDriver = null;
DesiredCapabilities cap = DesiredCapabilities.firefox();
FirefoxProfile profile = (new ProfilesIni()).getProfile("default");
// HERE cap.setCapability(FirefoxDriver.PROFILE, profile);
try {
System.out.println("trying ff");
remoteWebDriver = new RemoteWebDriver(new URL("http://" + host
+ ":4444/wd/hub"), cap);
} catch (MalformedURLException e) {
e.printStackTrace();
}
return remoteWebDriver;
}

What steps will reproduce the problem?
1. one can execute the code with the HERE line commented
2. now run the code with the HERE line not as a comment
3. look at the output of the selennium-server-standalone

What is the expected output? What do you see instead?
Expected a Firefox window opening.
Instead I have an exception on the terminal (will add as a comment)

Selenium version:
OS: Junit 4 Test with Selenium 2.11 on Linux within Eclipse. Windows XP
with selenium-server-standalone 2.11 and Firefox 7.0.1 on the
RemoteWebDriver site.

The error message is pretty clear: you need to allocate more heap space to
java (at least twice the size of the profile being transported is
recommended)

Sending the default profile is seldom a good idea: it contains all the
files that firefox has cached and is probably unnecessarily large. Better
is to prepare a skeleton profile that contains just the things you need and
transfer that across the wire.

I am still afraid there might be an issue. Setting -Xmx to 1024M die not
solve it for me. However, the profile is just 113 MB.

Using
firefoxProfile.addExtension(extension);
on a new profile solved it.
