DKPro NamedEntity ClassCastException

[Armin.Wegner]

Hello!

I'm getting a 

java.lang.ClassCastException: org.apache.uima.cas.impl.AnnotationImpl cannot be 
cast to de.tudarmstadt.ukp.dkpro.core.api.ner.type.NamedEntity 

using the annotator below in a CPE. It's a Maven project using

de.tudarmstadt.ukp.dkpro.core.stanfordnlp-gpl:1.6.1,
de.tudarmstadt.ukp.dkpro.core.io.text-asl:1.6.1, and
uimafit-core:2.1.0.



import org.apache.uima.analysis_engine.AnalysisEngineProcessException;
import org.apache.uima.cas.CAS;
import org.apache.uima.cas.Type;
import org.apache.uima.cas.TypeSystem;
import org.apache.uima.fit.component.CasAnnotator_ImplBase;

import de.tudarmstadt.ukp.dkpro.core.api.ner.type.NamedEntity;

public class CastError extends CasAnnotator_ImplBase {
        private Type mType;

        @Override
        public void process(CAS cas) throws AnalysisEngineProcessException {
                // The following line causes
                // Caused by: java.lang.ClassCastException: 
org.apache.uima.cas.impl.AnnotationImpl cannot be cast to 
de.tudarmstadt.ukp.dkpro.core.api.ner.type.NamedEntity
                NamedEntity neAnno = (NamedEntity) cas.createAnnotation(mType, 
0, 1);
        }

        @Override
        public void typeSystemInit(TypeSystem aTypeSystem) throws 
AnalysisEngineProcessException {
                super.typeSystemInit(aTypeSystem);
                mType = 
aTypeSystem.getType("de.tudarmstadt.ukp.dkpro.core.api.ner.type.Person");
        }
}

Any ideas?

Thanks,
Armin
