Erro JAXB

DevSolo · Junho 11, 2018, 5:24pm

Estou migrando um código meu de JDK 8 para JDK 10.
O aplicativo em questão é Web e utilizo o Spring e como servidor web uso o Wildfly 13.
No método problemático tento fazer uma desserialização de um XML.
A unica diferença entre um aplicativo e outro é a JDK, todas as bibliotecas usadas tem a mesma versão, excetuando algumas bibliotecas adicionais do JAXB.
Primeiramente a exceção:

o código que da problema

try
    {
          var file = new File("arquivo.xml");
          var context = JAXBContext.newInstance(ObjectFactory.class);
          var unmarshall = context.createUnmarshaller();
          var element = (JAXBElement<Clientes>) unmarshall.unmarshal(file);
          var cli = element.getValue();
        System.out.println(cli.getNome());
    } catch (JAXBException ex)
    {
        Logger.getLogger(XtlController.class.getName()).log(Level.SEVERE, null, ex);
    }

Então, cara, isso aqui é que causa o problema.
Em algum ponto, existe a tentativa de conversão do Cliente para o JAXBElement.

Tenho o mesmissimo código rodando no JDK 8. com a unica diferença de ter os tipos explicitos.

darlan_machado · Junho 11, 2018, 5:41pm

Vai ver é isso.
Este erro ocorre rodando que versão do java?

DevSolo · Junho 11, 2018, 5:48pm

Então apesar de tudo acredito que não seja o JDK, pois fiz um aplicativo de console com o mesmo rodando na JDK 10 e o codigo funciona, quero tentar entender, o que esta acontecendo. Estou dando uma olhada no JDK 10 e testando coisas simples como essa, não era pra ter erro por ser um funcionalidade basica, o JAXB no JDK 8 era incluido na JDK e agora na 9 e na 10 “esta sendo separado”, para definitivamente ser algo totalmente avulso na 11. MAS adicionei as bibliotecas JAXB e como disse fiz um aplicativo de console que funciona.
