[SHRINKDESC-131] Findbugs: Namespace

I solved this issue. Jesper is demanding this. 
I don't know the state since the reboot initiative. Let me know when I have to change something.

Hi Ralf,

I have these open - in order of priority from my PoV:

SHRINKDESC-131 Findbugs: Namespace

  - Our findbugs report for the project has a lot of errors due to this

SHRINKDESC-126 JavaDoc incorrect for parameters

  - Needs to be correct since the generator generates a public API

SHRINKDESC-133 Package documentation

  - Needed in order to improve public API description

SHRINKDESC-125 Add "exportAsString"-esque facility for Node SPI

  - Nice for debugging

SHRINKDESC-134 Temporary files aren't cleaned up

  - Maybe this one can be closed
