No bean introspection available for type XXX

[steventen]

Expected Behavior

Repository query should not throw exception. This same code works fine on Micronaut v4.2.x and previous versions.

Actual Behaviour

Run a simple query on repository causes io.micronaut.core.beans.exceptions.IntrospectionException

No bean introspection available for type [class xxxx] exception. Ensure the class is annotated with io.micronaut.core.annotation.Introspected

Steps To Reproduce

1. Create an entity class
2. Create an repository interface for the entity annotated with JdbcRepository that extends CrudRepository
3. Add a findByXXX query

An example can be found: https://github.com/steventen/micronaut-no-bean-introspection-issue

A simple test like this will reproduce the error.

Adding @Introspected as suggested by the error message wouldn't help.

Environment Information

• JDK 17
• Micronaut 4.3.x

It looks like some weird KSP bug; I will investigate it later. For now, you can declare the Jakarta Persistence annotations as an implementation dependency.
