Merge "Reduce technical debt"

Reduce technical debt

The last for technical debt I believe. The last try-with-resources I dare to
fix. Useless import that I missed last time. Did a couple of minor
reductions in cyclomatic complexity that I think are harmless.
And lastly introduce a new variable instead of reusing a parameter.
