Olá,
resolvi voltar ao meu passatempo de criar uma aplicação do tipo “Blog em 15 minutos” com VRaptor 3. Existe um método no meu controller que é assim:
@Get
@Path("/post/{id}")
public Post show(long id) throws RecordNotFound {
Post post = entityManager.find(Post.class, id);
if (post == null) {
throw new RecordNotFound("Couldn't find post with ID=" + id);
}
return post;
}
Pois bem, se eu utilizar como tipo primitivo “long”, surge a seguinte exceção:
java.lang.ClassFormatError: Arguments can't fit into locals in class file PostController$show$920210699$1

O mais estranho: se eu trocar para a classe wrapper Long, funciona normal; para o tipo primitivo int, também; para String, também; e para Integer, também. Apenas quando é utilizado o tipo primitivo long que dá erro.
Isso não seria um bug? Eu, particularmente, prefiro sempre usar tipos primitivos pra evitar problemas.
