RemoteWebDriver causing stackoverflow error when calling switchTo() method

Question

Selenium Version: 3.7.1

I am automating a java swing application and making use of remote web driver as follows:

DesiredCapabilities dc = new DesiredCapabilities();
dc.setBrowserName("java");
dc.setVersion(" ");
dc.setJavascriptEnabled(true);
dc.setPlatform(Platform.ANY);
javaDriverTest = new RemoteWebDriver(new URL("docker container url"), dc);

Everything works fine apart from the following:

javaDriverTest.switchTo().window(windowName);

and I subsequently get this error:

This doesn't happen all the time. But is quite frequent. Any idea how it can potentially be fixed?

@cruisepandey I have edited the original question to add more info. Please have a look. — Larry, Jun 27 '18 at 16:08
@SiKing, its simply a switchTo().window() call. I can't think of any kind of fix for that call in particular. Perhaps I need to find an alternative solution? — Larry, Jun 27 '18 at 16:09

It seems the issue is related to the way I started up the application i.e. I initially used the following:

export DISPLAY=:1.0
javaws -J -Dmarathon.agent=file:/root/Downloads/marathon-java-agent-5.1.4.0.jar.........

but when I added Xvfb to the command i.e.

Xvfb :1.0
export DISPLAY=:1.0
javaws -J -Dmarathon.agent=file:/root/Downloads/marathon-java-agent-5.1.4.0.jar.........

it fixed the issue. Therefore, I believe this issue is indeed not related to RemoteWebDriver, but actually to way the application under test is started.
