Consider the following annotation

@Qualifier
public @interface ConfigProperty {
    @Nonbinding
    String value() default "";
}


If I like to programmatically create an annotation instance then I can write

struberg

ConfigValue<Integer> port = config.resolve("myUrl)
                        .as(Integer.class)
                        .cacheFor(5,TimeUnit.Seconds)
                        .notifyOnChange(::somemethod);

...
port.get();

struberg

public Optional<String> getDings() {
  String dings = ...;
  return Optional.ofNullable(dings);
}

public void usageWithOptional(Optional<String> val) {
  String x = val.orElse("defaultValue");
  or
  String x = val.get() // and boom if missing instead of Validate.notNull

struberg

public class ConfigLocator implements Extension {
  private Config config;
  
  public void initConfig(@Observes BeforeBeanDiscovery bbd, BeanManager bm) {
    List<ConfigSource> collectedConfigSources = new ArrayList<>();
    bm.fireEvent(new CollectConfig(collectedConfigSources));
    this.config = ConfigProvider.newConfig()......;
    
    
    bm.fireEvent(config);

@ApplicationScoped
public class DynamicConfigUsageSample {

    private @Inject Config config;

    private ConfigValue<String>  serverUrlCfg;
    private ConfigValue<Integer> serverPortCfg

    @PostConstruct
    private void init() {

The following small changes allows to use < and > in asciidoctor code parts in reveal.js

-------
(function () {
    var optionKeys = ['attributes'];
    var defaultOptions = ['showtitle'];
    var sections = document.querySelectorAll('[data-asciidoctor]');
    var attributes, options;
    for (var i = 0, len = sections.length; i < len; i++) {
        var currentAttr = sections[i].getAttribute('data-attributes');

Hi Vlad!

The 140 char limit on Twitter isn't really helpful to make to the point statements. At least it seems you totally missed my 2nd tweet. But since the context between 2 tweets often gets lost I thus added a longer explanation as blog post https://struberg.wordpress.com/2016/10/15/tostring-equals-and-hashcode-in-jpa-entities/

I you have read my blog post carefully then you might notice that your first sentence is quite off from what I expressed. You missed that I am focusing on PORTABLE behaviour (which you as a Hibernate maintainer obviously don't care about) and on DEFAULT IDE generated behaviour (which will hit Hibernate as well).

To get things straight: most IDEs do a bad job in GENERATING a good toString(), equals() and hashCode() method. They usually just pick all the attributes. Those generated methods usually also include attributes which are @ElementCollections or @OneToMany fields. I guess you agree with me that touching those fields in e.g. toString() will also trigger lazyLoading even in
