https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) Having a model like: @Entity(name = "tpc_supert" ) @Inheritance(strategy = InheritanceType.TABLE_PER_CLASS) public static class TablePerClassSuperType { @Id @GeneratedValue private Long id; } @Entity(name = "tpc_subt" ) public static class TablePerClassSubType extends TablePerClassSuperType { } And then trying to execute: Query<?> query = session.createQuery( "delete from " + TablePerClassSuperType.class.getName() + " e where type( e ) = :type" ); query.setParameter( "type", TablePerClassSuperType.class ); query.executeUpdate(); results in: java.lang.NullPointerException at org.hibernate.query.sqm.sql.BaseSqmToSqlAstConverter.contextAllowsTreatOrFilterEntityNameUse(BaseSqmToSqlAstConverter.java:3129) at
