OPENNLP-675: Replacing sys out and sys err with log4j calls.
----
> Absence of logging and usage of System.out
> ------------------------------------------
>
> Key: OPENNLP-675
> URL: https://issues.apache.org/jira/browse/OPENNLP-675
> Project: OpenNLP
> Issue Type: New Feature
> Components: Sentence Detector, Tokenizer
> Reporter: Eugene Prystupa
>
> There seems to be no concept of logging used by the libraries. Instead
> System.out.println is hard-coded in many places where debug information using
> a logging framework would do it.
> This makes awkward to use the modules integrated into a different application
> (as it spams our logs or console).
> Is the usage of System.out in core classes (like GISTrainer) by choice? Or is
> it simply a technical debt? I am happy to work on it and provide a patch if
> this is a technical debt.
