Description

I have tried upgrading DKPro Core to the RC1 and most of
the tests work, however, in one case I get this message:

Caused by: opennlp.tools.util.InvalidFormatException: Model version 1.6.0 is not supported by this (1.7.0) version of OpenNLP!
        at opennlp.tools.util.model.BaseModel.validateArtifactMap(BaseModel.java:428)
        at opennlp.tools.chunker.ChunkerModel.validateArtifactMap(ChunkerModel.java:88)
        at opennlp.tools.util.model.BaseModel.checkArtifactMap(BaseModel.java:493)
        ... 48 more

The problematic model is a third-party chunker model:

I believe that 1.6.0 models should still work for 1.7.0, right?
