public DefaultExecutor()

    Default constructor creating a default PumpStreamHandler and sets the working directory of the subprocess to the current working directory. The PumpStreamHandler pumps the output of the subprocess into our System.out and System.err to avoid into our System.out and System.err to avoid a blocked or deadlocked subprocess (seeProcess).

```
    从接口复制的说明: Executor
    
    Checks whether exitValue signals a failure. If no exit values are set than the default conventions of the OS is used. e.g. most OS regard an exit code of '0' as successful execution and everything else as failure.
