Given:
* Batch fetch size
* Polymorphic entity with cache and relationships described below
* PreLoadEventListener which uses Hibernate.getClass(event.getEntity())
When
* Executing a simple HQL to list entities
Then
* IllegalStateException: Illegal pop() with non-matching JdbcValuesSourceProcessingState happens
