Hibernate Inheritance not persisting to database table

[shohruh-genius]

Describe the bug

@Entity
@Table(name = "test_parent")
@Inheritance(strategy = InheritanceType.JOINED)
class Parent(var name: String) : PanacheEntity()

@Entity
class Child(name: String) : Parent(name)

@GraphQLApi
@Name("test_inheritance")
class TestInheritanceGraphQLResource {
    @Mutation
    fun create(name: String) = withTransaction {
        Child(name).persist<Child>().awaitSuspending()
    }
}

database is postgresql 16

Expected behavior

It should save the data to the table when endpoint is called.

Actual behavior

It is not working on aws ecs which runs on ubuntu-latest

(p.s. it works on local devices which run on macos 15 and windows 11)

Hey,

Thanks for reporting.

To clarify, you're using Hibernate Reactive, right? Hard to say without the imports, but I guess awaitSuspending() gives us a clue.

As you can guess, other users -- and our own test suite -- are dealing with inheritance fine, so the issue must involve some specifics of your setup.

Please provide a reproducer (a simple Quarkus project demonstrating the issue). Preferably in Java since Kotlin is not my forte.

found the issue
when I added following property
quarkus.hibernate-orm.jdbc.statement-batch-size=20
Hibernate @Inheritance didn't work, it didn't persist the data

[yrodiere]

Thanks, but this is not normal behavior. The JDBC statement batch size shouldn't even interact with @Inheritance in any way.

Please provide a reproducer?

Closing for a lack of a reproducer.

If one becomes available, please add it and we can reopen the issue.
