Issue Type:	Bug
Affects Versions:	6.2.0.CR3, 6.2.0.CR4
Assignee:	Unassigned
Components:	hibernate-core
Created:	21/Mar/2023 07:25 AM
Priority:	Critical
Reporter:	Jones

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
