Using JpaRepository causes error in native code

[wabrit]

Describe the bug

Using the spring-data-jpa extension, it is possible to use JpaRepository in JVM builds. But in native builds there is a runtime error caused by missing methods from the interface.

For example with the repository definition

public interface ErewhonRepository implements JpaRepository<Erewhon, Long> { }

and injection of this interface into an application-scoped bean, then when running native the following error is reported:

java.lang.IllegalArgumentException: Cannot find method save[class Erewhon] on class ErewhonRepository_8003579965ca368f2bc90fccf68a67bef90d72b8Impl

Attaching @RegisterForReflection to the interface itself, or any of those in the inheritance hierarchy, does not appear to cure the issue.

Expected behavior

It should be possible to use JpaRepository in native as well as JVM quarkus applications.

Actual behavior

A java.lang.IllegalArgumentException: Cannot find method error is raised (see details above).

How to Reproduce?

Steps to reproduce the behaviour:

1. A minimal quarkus app with e.g. one REST entry point P.
2. An interface I derived from JpaRepository<E, Long> based on a simple entity E (could use h2 or other in-memory DB for convenience)
3. Make P call a method of an injected I (the actual method probably doesn't matter, it's just a trigger for Arc to go do work)

If built for JVM the call will succeed, but when run native there will be a java.lang.IllegalArgumentException: Cannot find method error when the endpoint P is hit.

Additional information

Switching from JpaRepository to PanacheRepository makes the issue go away.

[geoand]

I was not able to reproduce this.

Please attach a reproducer project when you get a chance so we can see exactly what's going on.

[wabrit]

Apologies - will put something together.

[wabrit]

Sorry for the delay - the simple reproducer I had hoped to put together does not reproduce the issue, so there's obviously something a little more subtle going on which will take some time to replicate.

[geoand]

Not a problem at all.

Closing as we did not get a reproducer
