             Summary: NPE when serializing a TokenNameFinder model trained with POSTaggerNameFeatureGeneratorFactory
                 Key: OPENNLP-1369
                 URL: https://issues.apache.org/jira/browse/OPENNLP-1369
             Project: OpenNLP
          Issue Type: Bug
            Reporter: Lucas Avanço


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>
  </generator>

 

This is the POS-tagger model used:
