quarkus: @Inject Injection into EntityListener not working

Describe the bug I do have JPA entities annotated with @EntityListeners. I @Inject some CDI bean (@RequestScoped in my case but happens for other scopes, too) into the EntityListener. The bean never gets injected, the reference is allways null.

Things I tried:

• placing some CDI scope annotation onto the entity listener.
• Tried different CDI scopes on the injected bean
• Tried all variants of injection: constructor-, setter- and attribute-injection on the listener

Expected behavior Instance of the CDI bean should get injected

Actual behavior The CDI bean reference is allways null resulting in a NPE when accessing some attribute of the bean.

To Reproduce See attached test case

Configuration

quarkus.datasource.url=jdbc:h2:tcp://localhost/mem:test
quarkus.datasource.driver=org.h2.Driver
quarkus.hibernate-orm.database.generation=drop-and-create

(Also happens with postgresql, drop-and-create is just for testing)

Environment (please complete the following information):

• Output of java -version: from 8 to 11
• Quarkus version or git rev: 1.2.0

Additional context Interestingly, when the CDI bean I want injected into the EntityListener ist injected somewhere else (e.g. some @ApplicationScoped bean), injection works. Possible causse: looks like Quarkus bean discovery does not regard EntityListeners as trigger for registering some bean during compile-time-initialization.

Example code:

src/main/java/…

package org.acme;

import java.util.UUID;

import javax.persistence.Entity;
import javax.persistence.EntityListeners;
import javax.persistence.Id;
import javax.persistence.Version;

@Entity
@EntityListeners(FooListener.class)
public class FooEntity {

	@Id
	private String id = UUID.randomUUID().toString();
	@Version
	private long version;
	private String data;

	// getters/setters omitted for brevity
}

package org.acme;

import javax.enterprise.context.Dependent;
import javax.inject.Inject;
import javax.persistence.PrePersist;

// also happens with @Dependent
public class FooListener {

	@Inject
	private FooBean fooBean;

	@PrePersist
	public void prePersist(FooEntity entity) {
		entity.setData(fooBean.pleaseDoNotCrash());
	}
}

package org.acme;

import javax.enterprise.context.RequestScoped;

@RequestScoped
public class FooBean {

	public String pleaseDoNotCrash() {
		return "Yeah!";
	}
}
