Hibernate-Reactive: ClassCastException EmbeddableInitializerImpl to ReactiveInitializer

[ITrium-Salah]

Describe the bug

When migration from Quarkus 3.13.3 to any quarkus 3.14.X version a classe cast expression occured when using @Embeddable/@EmbeddedId.

Expected behavior

No exception should be thrown.

Actual behavior

java.lang.ClassCastException: class org.hibernate.sql.results.graph.embeddable.internal.EmbeddableInitializerImpl cannot be cast to class org.hibernate.reactive.sql.results.graph.ReactiveInitializer (org.hibernate.sql.results.graph.embeddable.internal.EmbeddableInitializerImpl and org.hibernate.reactive.sql.results.graph.ReactiveInitializer are in unnamed module of loader io.quarkus.bootstrap.classloading.QuarkusClassLoader @10feca44)

    at org.hibernate.reactive.sql.results.internal.ReactiveStandardRowReader.lambda$coordinateInitializers$28(ReactiveStandardRowReader.java:376)

How to Reproduce?

My code is simple.

class A extends PanacheEntityBase{
    @EmbeddedId 
    B id;
 
}
@Embeddable
class B implements Serializable{
    @Column(nullable=false)
    String c1;
    @Column(nullable=false)
    String c2;
}

Http Route
return A.listAll();

Output of uname -a or ver

Output of java -version

No response

Quarkus version or git rev

3.14.4

Build tool (ie. output of mvnw --version or gradlew --version)

This should be fixed by #43348

Any chance to have this backported to 3.15?
