When I run this programm, I always get exitCode == 255.
$ java -version

I found it with other code, but this is my small testcase to reproduce it.

Can people reproduce this?


import java.io.IOException;

final class ExecTest {

     public static void main(String[] args) throws IOException,  
InterruptedException {
         Runtime rt = Runtime.getRuntime();
         Process p = rt.exec("/bin/ls");
         int exitCode = p.waitFor();
         System.out.println("ExitCode: " + exitCode);
