Start & Stop Appium Server Programmatically using Java (MAC OSX)

AppiumServer.java

}

The start and stop methods are good to go with if we have only one instance of appium server. What if we have multiple appium server launched and we want to stop a particular node. using given code to stop server stops all the servers launched.

welcome your suggestions...

I'm also having same question, what we can do if we have 2 appium server instance. @benz-philip
