I don't think there is a direct way to test it. Did you rad the Java doc for Precess members, there may be a hint, but cannot be a direct way. But working on a thread it's possible.

I explain the way how i did that in Java on linux with the help of shell script command:

run the command from java application which is:

String command="ps -A -U "+System.getProperty("user.name")+" -d";
try {
      String line;
      Process p = Runtime.getRuntime().exec(command);
      BufferedReader input =new BufferedReader(new InputStreamReader(p.getInputStream()));
      while ((line = input.readLine()) != null) {
        System.out.println(line);
      }
      input.close();
    }catch (Exception err) {
      err.printStackTrace();
    }

Then read line by line the output and check if the process was launched by you.

You could run int = Process.exitValue(); and see if it throws an IllegalThreadStateException.
