Spring Boot > 3.5.0 + Spring Data JPA + HotSwapAgent + Vaadin causes injection error

I’ve tried multiple project setups using Vaadin Start, Spring Initializr, and various GitHub example repositories. Every project setup (be it Gradle or Maven) with Spring Boot > 3.5.0 and Spring Data JPA throws exceptions when trying to inject repositories with CDI and using Debug mode with HotSwapAgent:

error defined in @EnableJpaRepositories declared on JpaRepositoriesRegistrar.EnableJpaRepositoriesConfiguration: null

When downgrading Spring Boot to version 3.5.0, HotSwapAgent works as expected and no exceptions occur.

Environment:

  • IntelliJ IDEA 2024.3.1.1 Ultimate Edition
  • Vaadin plugin 1.5.1
  • Spring Boot 3.5.3
  • Vaadin 24.8.3

What I tried:

  • Tried different versions of Vaadin.
    Vaadin version does not seem to have any impact on the problem.
  • Tried multiple Spring Boot versions.
    Using Spring Boot 3.5.0 works, but any version > 3.5.0 causes this issue.

Questions:

  • Is this a known compatibility issue with HotSwapAgent + Spring Boot > 3.5.0?
  • Are there any workarounds or recommended configurations for using HotSwapAgent with newer Spring Boot versions?

Thanks in advance for your help!
