Thanks for your contribution.
But I failed to run an unit test for TestNetTypes as following:
```
-------------------------------------------------------------------------------

java.lang.AssertionError:

```
The strange thing is that it only is reproduced on console. I found that it
had run successfully with IDE.
Could you check this problem on your development environment?
