How to run selenium standalone server with Edge webdriver? - selenium

Question

I'm trying to run Selenium tests against Edge, in the same way I successfully run with Chrome or Internet Explorer 11 but it fails.
What I do is starting the standalone selenium and it works fine:
java -Dwebdriver.edge.driver=C:\tmp\msedgedriver.exe -jar C:\tmp\selenium-server-standalone-3.141.59.jar -port 4445
But when I run the Selenium tests, it fails with the error below:
I've tried to add "-DbrowserName=edge" but it does not make any difference.
Is there something I've missed?

Here's the java code I wrote to use Feature on Demand EdgeDriver. This has not been tested, so if you use it, let me know if it works:
String windir = System.getenv("windir");
boolean is64bit = false;
is64bit = (System.getenv("ProgramFiles(x86)") != null);
String edgeDriverPath = windir + "\\SysWOW64\\MicrosoftWebDriver.exe";
if (!is64bit)
{
edgeDriverPath = windir + "\\System32\\MicrosoftWebDriver.exe";
}
System.setProperty("webdriver.edge.driver", edgeDriverPath);
EdgeOptions edgeOptions = new EdgeOptions();
//edgeOptions.setPageLoadStrategy(stringPageLoadConstant);
try {
driver = new EdgeDriver(edgeOptions);
}
catch (Exception ex)
{
System.out.println ("Problem launching EdgeDriver: " + ex.toString());
}
