Close appium 1.6.0 server programmatically on mac

Until the 1.6.0 version was released I used successfully this code to stop the server:

public static void stopServer() {
String[] command = { “/usr/bin/killall”, “-KILL”, “node” };
try {
System.out.println(“Appium server stopped.”);
} catch (IOException e) {

Now, when using the 1.6.0, it doesn’t do the trick…
Any idea why? What has changed?

Thanks for the reply…

No one can answer?
It is quite urgent…
