> Reporter: Lucas Avanço
> Priority: Major

> 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*
>
> <generator
> class="opennlp.tools.util.featuregen.WindowFeatureGeneratorFactory">
> <int name="prevLength">2</int>
> <int name="nextLength">2</int>
> <generator
> class="opennlp.tools.util.featuregen.POSTaggerNameFeatureGeneratorFactory">
> <str name="model">pt-pos-perceptron.zip</str>
> </generator>

> This is the POS-tagger model used:
