I have a field that's in a superclass and is supposed to be always stored

 
                                                    @Entity
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(name = "DTYPE", discriminatorType= DiscriminatorType.STRING, length = 3)
@DiscriminatorOptions(force=true)
@Indexed
public abstract class MySuperClass implements Serializable{

	@Column(length=255)
	@Field(index=Index.YES,analyze=Analyze.YES,store=Store.YES,indexNullAs=Field.DEFAULT_NULL_TOKEN)
	@Size(max=255) @CheckXSS @FilterHTML
	public String getLabel(){
		return label;
	}
 
                                                

 
                                                    	BooleanJunction mj = qb.bool()
		.must(new MatchAllDocsQuery())
		.must(
			qb.keyword().onField("label").matching(SearchConstants.NULLTOKEN).createQuery()
		).not();
		
	return fts
		.createFullTextQuery(
				mj.createQuery(),
				MyClass.class)
		.setProjection(ProjectionConstants.ID, "label")
		.setResultTransformer(new StaticAliasToBeanResultTransformer(MyClassVO.class,
				new String[]{"id", "label"}
				))
		.setFirstResult(start)
		.setMaxResults(max)
		.list()
		;
 
                                                

However, on subclasses it is simply not stored at all when null and subsequently generates a nullpointer exception on the fieldbridge

 
                                                    	Caused by: java.lang.NullPointerException
	at org.hibernate.search.bridge.builtin.impl.NullEncodingTwoWayFieldBridge.get(NullEncodingTwoWayFieldBridge.java:32)
	at org.hibernate.search.bridge.util.impl.ContextualExceptionBridgeHelper$TwoWayConversionContextImpl.get(ContextualExceptionBridgeHelper.java:123)
	... 29 more

Is it possible that indexNullAs does not work on abstract superclass fields?
