Received object of type org.postgresql.util.PGobject

I can insert geometry data into database from my code, but I can only query the data using an SQL editor, like PGAdmin III. I can't retrieve geometry data back to my code. Every attempt ends up with: "Received object of type org.postgresql.util.PGobject". Even running a simple query to test if two geometry values are equal, I get this error.

I'm using: - Hibernate 5.2 - PostgreSQL 9.6 - Postgis 2.3 - JDBC driver PostgreSQL 42.1.4 - Wildfly 11 (CR1)

Here is the model class:

import java.io.Serializable; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; import com.vividsolutions.jts.geom.Point; import com.vividsolutions.jts.geom.Geometry; import com.vividsolutions.jts.geom.LineString; import com.vividsolutions.jts.geom.Polygon; import javax.persistence.Column; @Entity public class PontodeInteresse implements Serializable { private static final long serialVersionUID = 1L; @Id @GeneratedValue(strategy = GenerationType.SEQUENCE) private Long id; private String descricao; @Column(columnDefinition = "geometry(Point,4326)") private Point ponto; @Column(columnDefinition = "geometry(LineString,4326)") private LineString linha; @Column(columnDefinition = "geometry(Geometry,4326)") private Geometry geometry; @Column(columnDefinition = "geometry(Polygon,4326)") private Polygon poligono; 

The POM file:

<dependencies> <dependency> <groupId>org.primefaces</groupId> <artifactId>primefaces</artifactId> <version>6.1</version> </dependency> <dependency> <groupId>javax</groupId> <artifactId>javaee-web-api</artifactId> <version>6.0</version> <scope>provided</scope> </dependency> <dependency> <groupId>com.vividsolutions</groupId> <artifactId>jts</artifactId> <version>1.13</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-spatial</artifactId> <version>5.2.10.Final</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> <version>5.2.10.Final</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-entitymanager</artifactId> <version>5.2.10.Final</version> </dependency> <dependency> <groupId>dom4j</groupId> <artifactId>dom4j</artifactId> <version>1.6.1</version> <scope>provided</scope> </dependency> </dependencies> 

Inside persistence.xml file, I'm using this dialect property:

<property name="hibernate.dialect" value="org.hibernate.spatial.dialect.postgis.PostgisPG95Dialect"/> 

PS: I have already tried the PostgisDialect

Finally, the method with a simple test query:

public void testar() { try { GeometryFactory gf = new GeometryFactory(); LinearRing shell = gf.createLinearRing(new Coordinate[] { new Coordinate(-43.56006145477295,-22.8861191211294), new Coordinate(-43.55607032775879,-22.8861191211294), new Coordinate(-43.55607032775879,-22.88279796969916), new Coordinate(-43.56006145477295,-22.88279796969916), new Coordinate(-43.56006145477295,-22.8861191211294)}); LinearRing[] holes = new LinearRing[0]; Polygon polygon = gf.createPolygon(shell, holes); polygon.setSRID(4326); Query q = entityManager.createQuery("from PontodeInteresse where equals(geometry, :geo) = true").setParameter("geo", polygon); List<PontodeInteresse> pontos = q.getResultList(); } catch(Exception e) { System.out.println(e.getMessage()); }//try } 

I'm completely lost here, running out of ideas. Please help. Thanks
