      CDI transactional observer methods works fine. So, the following "@Observes @Destroyed(TransactionScoped.class)" method can be used as a possible workaround:

      import javax.enterprise.context.Destroyed;
import javax.enterprise.context.Initialized;
import javax.enterprise.event.Observes;
import javax.transaction.Transaction;
import javax.transaction.TransactionScoped;
import org.jboss.logging.Logger;

public class TransactionScopedObserverBean {
    private static final Logger log = Logger.getLogger(TransactionScopedObserverBean.class);

    void init(@Observes @Initialized(TransactionScoped.class) final Object event) throws Exception {
        // do some initilize tasks after TransactionScoped bean has been initialized
    }   

    void destroy(@Observes @Destroyed(TransactionScoped.class) final Object event) throws Exception {
        // do some cleanup tasks after TransactionScoped bean has been destroyed (= after commit or rollback on JTA transaction)
    }   
}

      1. Extract the attached reproducer.zip
      2. Start Quarkus dev mode

      $ cd reproducer
$ ./mvnw clean compile quarkus:dev

      3. Send a request

      $ curl -v http://localhost:8080/hello

      Then, you will see the following log messages that indicate @PreDestroy destroy method is not invoked:

      INFO  [com.exa.qui.GreetingService] (executor-thread-1) GreetingService initialized.

      As mentioned in the guide, quarkus-narayana-jta extension provides javax.transaction.TransactionScoped support.

      However, even if quarkus-narayana-jta extension is enabled, @PreDestory method is not invoked for @TransactionScoped bean at the end of the transaction (commit or rollback). (@PostConstruct method is invoked correctly, though.)

      import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;
import javax.transaction.TransactionScoped;
import org.jboss.logging.Logger;

@TransactionScoped
public class ExampleTransactionalScopeBean implements ExampleTransactionalScope {

    private static final long serialVersionUID = 1L;
    private static final Logger log = Logger.getLogger(ExampleTransactionalScopeBean.class);
    private long value;

    @PostConstruct
    void init() {
        this.value = System.currentTimeMillis();
        log.infof("ExampleTransactionalScopeBean initialized. bean value is %s", this.value);
    }

    @PreDestroy
    void destroy() {
        log.infof("ExampleTransactionalScopeBean destroyed. bean value is %s", this.value);
    }

    public long getValue() {
        log.infof("ExampleTransactionalScopeBean value = %s", this.value);
        return value;
    }

}
