Description

After introducing slf4j in OpenNLP, we should discuss the log levels.

We have a lot of different variants in the code base:

• System.err
• System.out
• "[WARN] ..." via System.err / System.println
• "[ERROR] ..." via System.err / System.println

Goal is to define / discuss proper log levels as provided by SLF4J (trace, debug, etc.)
