Describe the bug

When defining a PanacheRepository outside of an entity, I get a compilation error. It seems it tries to implement the interface infinity times.

Expected behavior

The compilation suceeeds with only 1 <repository>_ class (with one underscore).

Actual behavior

I get an error:

[ERROR] COMPILATION ERROR : 
[INFO] -------------------------------------------------------------
[ERROR] Problem opening file to write MetaModel for MyEntityRepository________________________________________________________________________________________________________________________________________________________________________________________________________________________________________: /Users/rokkolesa/Medius/workspaces/workspace-sandbox/panache-next-multiple-impl-bug/target/generated-sources/annotations/org/acme/MyEntityRepository_________________________________________________________________________________________________________________________________________________________________________________________________________________________________________.java: File name too long

It seems that an implementation is generated, but then that file is used to generate another one.. and so on and so on until we hit the file name length constraint.

How to Reproduce?

panache-next-multiple-impl-bug.zip

The simplest reproducer is this:

1. run
   quarkus create app panache-next-multiple-impl-bug -P 3.32.2 -x=io.quarkus:quarkus-hibernate-panache-next

2. Add a file

public class MyEntityRepository
        implements PanacheRepository<MyEntity>
{
}

3. run
   ./mvnw clean compile

This yields the error in console. Upon checking the target, I then see this:

Additional information

This works fine in Quarkus 3.23.1 and it seems that hibernate-orm version 7.2.5 brought in this error.

Quarkus 3.23.1 uses hibernate 7.2.4 and 3.23.2 uses hibernate 7.2.6 bringing in this error.
