This is the test case:
===================
<pre>
public class TestProc {
    public static void main(String... args) {
        ProcessHandle ph = ProcessHandle.current();
        ProcessHandle.Info info = ph.info();
        System.out.println("Pid = " + ph.pid());
        System.out.println("CommandLine: ");
        if (info.commandLine().isPresent()) {
            System.out.println(info.commandLine().get());
        }
        System.out.println("Command:");
        if (info.command().isPresent()) {
            System.out.println(info.command().get());
        }
        System.out.println("Arguments: ");
        if (info.arguments().isPresent()) {
            for (String s : info.arguments().get()) {
                System.out.println(s);
            }
        }
    }
}
