Would you find time to also take a look on my other reported problem with hibernate?

Thanks for the reproducers, in the original description I think I overlooked the fact that the inheriting class is package protected. I can now reproduce both issues, and indeed they appear to be a bug in Hibernate, potentially related to bytecode enhancement.

Hello Jan,
Thank you for your response, I created example test with usage of hibernate test case templateshibernate orm demo mapped super class - read.zip
Could you take a look on it?
If you will change visibility of Inheriting class to public the problem will gone.

I’ve tried this out on the main branch and it works fine, so I would wager that this is either a bug in Spring or maybe a configuration issue. In either case if you are convinced that this is a bug in Hibernate, please provide a pure Hibernate reproducer demonstrating that. You can use the hibernate template project to make this easier ( )
Edit: also tried it on the 6.2.2 tag which is what SB 3.0.0 includes (iinm), and there also it seems to work as expected.
java.lang.NoSuchMethodErroris thrown when reading entity extending other class in different package,when both classes (inherited and inheriting) are in same package problem disappears
Problems was noticed in Hibernate 6.2.3.Final with Spring Boot 3.0.0, In Hibernate 5 function worked correctly. (I am migrating my application to new Spring Boot 3.0.0)
To reproduce problem use attached example application, execute get endpoint
