L'amélioration de Javassist a échoué

Question

J'utilise Jboss IDE comme IDE. J'ai créé un projet Hibernate. et je reçois cette erreur lors du déploiement de mon .har (projet Mise en veille prolongée):

Answer 1

Lorsque vous obtenez des traces de pile avec ce en elle:

java.lang.NullPointerException 
at org.jboss.mx.loading.RepositoryClassLoader.findClass(RepositoryClassLoader.java:623) 

Cela signifie généralement que le classloader de JBoss lui-même est entré dans un état irrécupérable, et le chargement de certaines classes de base tombe en panne, ce qui arrive parfois après beaucoup des déploiements à chaud. Dans mon expérience, il est généralement corrigé par un redémarrage de JBoss.

Answer 2

La trace de la pile est assez complexe, vous feriez mieux de demander aux développeurs JBoss sur les listes de diffusion JBoss/forums, ou ouvrir un rapport de bogue (étant donné qu'il existe une exception java.lang.NullPointerException, c'est sûrement un bug).

Quoi qu'il en soit, étant donné que l'erreur est signalée dans:

org.jboss.mx.loading.RepositoryClassLoader.findClass(RepositoryClassLoader.java:623) 

il y a un problème lors du chargement de classe, tout en recherchant une certaine classe. Vous pouvez regarder les sources de org.jboss.mx.loading.RepositoryClassLoader (ligne 623) pour voir si vous trouvez quelque chose d'utile, ou demander directement de l'aide ailleurs.

Answer 3

Vous devriez être utiliser cette propriété dans hibernate.cfg.xml

<property name="hibernate.bytecode.use_reflection_optimizer">false</property> 

s'il n'y a aucune raison à l'aide javaassit.jar, devrait supprimer ce fichier jar de chemin de génération de projet, que tout le monde peut le résoudre facilement depuis J'ai résolu de cette façon.

merci; thihasoe

Answer 4

Vérifiez la liste:
1. Vous devez avoir dafault constructeur sans-arg
2. Constructeur doit être publique
