New entities are not correctly registered when using Spring

[Artur-]

Test case: https://github.com/Artur-/spring-jpa-test

After launching DemoApplication and opening http://localhost:8080 you should see

EntityManager knows about these entities: [Entity1]

After copying Entity1.java to Entity2.java and replacing all 1s with 2s` in the file, you should be able to reload the page and see

EntityManager knows about these entities: [Entity1, Entity2]

However, you will still see

EntityManager knows about these entities: [Entity1]

even though HotswapAgent outputs

HOTSWAP AGENT: 11:04:43.913 RELOAD (org.hotswap.agent.plugin.hibernate_jakarta.HibernateRefreshCommands) - Hibernate EntityMangerFactory configuration refreshed.

Side note: If you use JRebel, then it works as expected
