ClassCastException in ReactiveEmbeddableInitializerImpl when using an EmbeddedId which contains a reference to another entity #47536
Description
Describe the bug
Given a setup where I have an entity FooEntity which has an EmbeddedId FooId, and FooId contains a reference to BarEntity, then trying to query FooEntity through Panache causes the following ClassCastException:
[ERROR] org.acme.hibernate.orm.panache.ReproTest.test(TransactionalUniAsserter) -- Time elapsed: 0.124 s <<< ERROR!
java.lang.ClassCastException: class org.hibernate.sql.results.graph.entity.internal.EntitySelectFetchInitializer cannot be cast to class org.hibernate.reactive.sql.results.graph.ReactiveInitializer (org.hibernate.sql.results.graph.entity.internal.EntitySelectFetchInitializer and org.hibernate.reactive.sql.results.graph.ReactiveInitializer are in unnamed module of loader io.quarkus.bootstrap.classloading.QuarkusClassLoader @4cc7d00d)
