Hibernate 6.2.2.Final fails in Native Image with UnsupportedFeatureError: No classes have been predefined…

After upgrading to Hibernate 6.2.2.Final (from 6.1.x), a native image startup fails with:

com.oracle.svm.core.jdk.UnsupportedFeatureError: No classes have been predefined during the image build to load from bytecodes at runtime.

The LocalContainerEntityManagerFactoryBean is defined manually:

    @Bean(name = "db1EntityManagerFactory")
    EntityManagerFactory db1EntityManagerFactory(@Qualifier("db1ServerDataSource") DataSource db1ServerDataSource) {

        Map<String, Object> properties = new HashMap<>();
        properties.put("hibernate.hbm2ddl.auto", "create-drop");
        properties.put("generate-ddl", "true");
        properties.put("hibernate.dialect", "org.hibernate.dialect.H2Dialect");

        LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();
        emf.setDataSource(db1ServerDataSource);
        emf.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
        emf.setPersistenceUnitName("db1Persist");
        emf.setPersistenceProviderClass(HibernatePersistenceProvider.class);
        emf.setPackagesToScan("org.matthenry87.nativetesting.api.db1");
        emf.setJpaPropertyMap(properties);
        emf.afterPropertiesSet();

        return emf.getObject();
    }
