      If you try to launch a blank command  ('  ') using Launch.ProcStarter#cmdAsSingleString, an ArrayIndexOutOfBoundException is thrown.

      Example of command invocation:

      launcher.launch()
    .cmdAsSingleString("   ")
    .envs(computer.getEnvironment())
    .readStdout()
    .pwd(rootPath)
    .start();

      Exception thrown:

      java.lang.ArrayIndexOutOfBoundsException: 0

      This exception is odd, and difficult to understand. In my understanding, the cause of the error (invalid command) should be more clear, and ideally, validated sooner.
