Hibernate search 4.2.0.Beta2 - sort-by-distance exception

I'm trying to use the new functionality: Spatial Queries sorted by distance

This is my query:

Code:

       final QueryBuilder builder = fullTextEntityManager.getSearchFactory().buildQueryBuilder().forEntity( Myclass.class ).get();
   
         double centerLatitude= lat.doubleValue();
         double centerLongitude= lng.doubleValue();
   
         Query luceneQuery = builder.spatial().onCoordinates( "location" ).within( radius, unit ).ofLatitude( centerLatitude ).andLongitude( centerLongitude ).createQuery();
      
         FullTextQuery hibQuery = fullTextEntityManager.createFullTextQuery( luceneQuery,   Myclass.class );
                        //begin - distanceSort block
         Sort distanceSort = new Sort( new DistanceSortField( centerLatitude, centerLongitude, "location" ) );
         hibQuery.setSort( distanceSort );
         hibQuery.setProjection( FullTextQuery.THIS, FullTextQuery.SPATIAL_DISTANCE );
         hibQuery.setSpatialParameters( centerLatitude, centerLongitude, "location" );
                        //end - distanceSort block
         hibQuery.setFirstResult(5*index);
         hibQuery.setMaxResults(5);      
              hibQuery.getResultList();

The code gives me this java exception On "hibQuery.getResultList()"

java.lang.ArrayIndexOutOfBoundsException: 10

at org.hibernate.search.jpa.impl.FullTextQueryImpl.getResultList(FullTextQueryImpl.java:160)

My query without "distanceSort block code" works very well, and gives me 2 result records.
It is my code problem or it is a hibernate search bug?

Hi,
I think you've hit one of:
https://hibernate.onjira.com/browse/HSEARCH-1219 (a patch was proposed on github - not merged yet but you're welcome to try it out: links on JIRA)
https://hibernate.onjira.com/browse/HSEARCH-1220 (resolved - welcome to try master)

Would you be able to verify them or create a unit test? Otherwise you could wait for the next tag which will include both, that will happen in two weeks.

Many thanks for your answer, I'm sure that my problem is due to what is reported in the bug
https://hibernate.onjira.com/browse/HSEARCH-1219 I will wait for the next release and I will do more tests.
