    indeed. very thoughtless of me.
    Problem was I was trying to run the following command on linux through java: 
    ls -f /proc/<pid>/fd

    the solution is to use
    exec(String cmd, String[] envp, File dir)
    which allows to specify which directory in which to run the command.
    File fd_dir = new File("/proc/" + pid + "/fd");
Process p = Runtime.getRuntime().exec("ls -l", null, fd_dir);

    Why not use java.io?
