> There is an issue of null pointer when trying to serialize a TokenNameFinder model trained using as one of feature generators POSTaggerNameFeatureGeneratorFactory.
> In this method  opennlp.tools.util.model.{*}BaseModel#serialize{*}(java.io.OutputStream) there is a for which iterates over the artifactMap of the POS-model that must be serialized together, but a NPE occurs because *generator.featuregen* is not found inside of *pt-pos-perceptron.zip*
