Broken unit tests

```
To replicate:
1. git pull (get latest from MASTER)
2. on Windows 7 machine (64 bit), run unit tests through Maven.
3. You will see the following failures:

The Maven build now fails on a few unit tests: (I did "git pull" first):

Results :

Failed tests:

Also - one other failure seen when running Maven test through Git shell (on
same windows machine):

Results :
