java.io.EOFException on urls that return content-length: 0

[smatei]

Hi,

I see java.io.EOFException in the console when I execute the following code:

` JBrowserDriver driver = new JBrowserDriver();

			driver.get("https://www.bing.com/");
			
			System.out.println(driver.getStatusCode());
			
			System.out.println(driver.getPageSource());
			
			driver.close();`

Console output:

Debugging this issue, I can see one of the urls returning gzip encoding with content-length 0.

I think that in the method com.machinepublishers.jbrowserdriver.ResponseHandler.handleResponse we should return if the content-length of the response is 0, and do not read any input stream.
