Reformat a lot of code...
Modify some code, and stumble upon .toString() tests again

One string output of a structured POJO is modified and you find yourself
rewriting a s*load of _String_ outputs as a results.

This is not sustainable!
Reformat ErrorUtils; simplify, add TODOs...

There is some very annoying adherence, even in that code!
ErrorUtils: more reformatting, TODOs etc
More reformatting...
