=> AGPL 3.0

We need to decide how to handle this...

https://opensource.org/licenses/AGPL-3.0
https://softwareengineering.stackexchange.com/questions/107883/agpl-what-you-can-do-and-what-you-cant
It seems you have to license this as AGPL as well... or follow how Spark handles this (recommended):
https://github.com/apache/spark/blob/dba2ca2c129b6d2597f1707e0315d4e238c40ed6/LICENSE#L239
with exclusion: https://github.com/apache/spark/blob/f44c8a843ca512b319f099477415bc13eca2e373/mllib/pom.xml#L102
Check Owen's comment: https://issues.apache.org/jira/browse/SPARK-1406

I see that https://github.com/jpmml/jpmml-evaluator README says "other licenses available on request". I'm not sure to which extend they can accept Apache/BSD licensing in the context of use by an Apache Licensed project.

@cjolif you are right, I will check and see how it goes with jpmml.
