What steps will reproduce the problem ?

Steps to reproduce the behavior:

1. Create an entity class with appropriate structure that has inner static class that's used as @EmbeddedId;
2. Build the project to see the graph is generated

What is the expected output ?

Graphs for entity and composed entity id are generated

What happens instead ?

Build failed. Graph is not generated. Issue: package CompositeIdEntityGraph does not exists in CustomEntityGraph

Environment

• spring-boot-starter-data-jpa: 3.5.4
• hibernate-core: 6.6.22.Final
• spring-data-jpa-entity-graph: 3.5.0

Additional context

Real case example:

@Entity
@Setter
public class Custom {
 @EmbeddedId
 CompositeId id;
 @ManyToOne
 @MapsId("firstObjectId")
 @JoinColumn(...)
 FirstObject fo;
 @ManyToOne
 @MapsId("seconfObjectId")
 @JoinColumn(...)
 SecondObject so;
 @Embeddable
 @Getter
 public static class CompositeId implements Serializable {
 UUID firstObjectId;
 UUID seconfObjectId;
 }
}

WA: It works if class is not static and placed outside it's root entity.

According to documentation, static classes are allowed to be used with @Embedded/@Embeddable annotations
