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

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');

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

public class JaxWsRegistrationExtension implements Extension {

    private List<AnnotatedType> webServices = new ArrayList<>();

    public void collectWebServices(@Observes @WithAnnotations(WebService.class) ProcessAnnotatedType<?> pat) {
        if (pat.getAnnotatedType().isAnnotationPresent(Path.class) && !pat.getAnnotatedType().getJavaClass().isInterface()) {
            webServices.add(pat.getAnnotatedType());
        }
    }
