In the source code there is for loop to pick up the right port this leads to various outputs in the console trying to start a webserver.

It would be a better option to add function to retrieve a random open port for this.

Something like:

public static int findFreePort() {
ServerSocket socket= null;
try

{ socket= new ServerSocket(0); return socket.getLocalPort(); }

catch (IOException e) {
} finally {
if (socket != null) {
try

{ socket.close(); }

catch (IOException e) {
}
}
}
return -1;
}
(this function template is taken from org.eclipse.jdt.launching.SocketUtil)

Best regards,
