Build tests failing with mvn clean test

[kinow]

Hi,

As commented on pull request #1, my environment seems to have problems running the tests. I am on branch master.

Running: mvn clean test with:

Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-11T05:41:47+13:00)

Which is basically Ubuntu LTS with Oracle JDK 1.8. It fails with the following errors:

There are a few places that inspecting the code in Eclipse, the IDE had a warning about possible NPE. It seems to happen indeed in some places in the log output.

Sorry, that was my mistake. I had set these tests to ignore on a local branch which I forgot to commit on master. These tests broke during the last refactoring and I haven't had the time to look deeper into it. So far I have not yet understood what the exact problem is.
