SqmCteRoot.toString() always produces NullPointerException

Description

org.hibernate.query.sqm.tree.domain.SqmCteRoot extends org.hibernate.query.sqm.tree.from.SqmRoot and inherits the toString() method from it.

The toString() method calls getEntityName() which in turn calls getModel().getHibernateEntityName().

But SqmCteRoot overrides getModel() and returns null.

which causes the toString() method to always fail with a java.lang.NullPointerException.

I noticed this when I changed my log level to TRACE and org.hibernate.query.hql.internal.DomainPathPart.resolvePathPart() tried to log a SqmCteRoot object.

I think that a workaround could be to override the toString() method as well.

It is hard for me to construct a test case because I am not sure what toString() should produce.

Hi ,

we just need a reproducer that throws the NullPointerException.

You can use our test case template: https://github.com/hibernate/hibernate-test-case-templates/blob/master/orm/hibernate-orm-6/src/test/java/org/hibernate/bugs/JPAUnitTestCase.java to create a reproducer.

 

Thanks.
