Closing all open command prompt leads to error in forked process in testNG - selenium

Question

I am using testNG for mobile automation and I want to close multiple command prompts(appium servers) which i launched. For this, I am using the below code
#AfterSuite
public void closeCommandPrompts() throws IOException, InterruptedException{
System.out.println("After suite");
Thread.sleep(8000);
Runtime.getRuntime().exec("taskkill /F /IM node.exe");
System.out.println("closed node.exe");
Runtime.getRuntime().exec("taskkill /F /IM cmd.exe");
The last line if I commnet it out works fine, however if they are not commented it gives an error in the forked process.
I guess testNG is internally using command prompt which i am trying to close when iam using taskkilll in #aftersuite.
Please help me in getting some work around.

You can use following code :
CommandLine command = new CommandLine("cmd");
command.addArgument("/c");
command.addArgument("taskkill");
command.addArgument("/F");
command.addArgument("/IM");
command.addArgument("node.exe");
DefaultExecuteResultHandler resultHandler = new DefaultExecuteResultHandler();
DefaultExecutor executor = new DefaultExecutor();
executor.setExitValue(1);
try {
executor.execute(command, resultHandler);
System.out.println("Stopped appium node ! ");
} catch (IOException e) {
System.out.println("FAIL => Unable to stop appium server "+e.getMessage());
e.printStackTrace();
}
