J'utilise le module de servlet Guice et j'essaie de ne faire fonctionner que le filtre de base et l'écouteur. Lorsque je démarre mon conteneur de servlets, j'obtiens une java.lang.IllegalAccessException enveloppée dans une AssertionError.Le projet Guice Servlet échoue avec IllegalAccessException au démarrage
Fondamentalement, ce qui semble se produire est que Guice essaye d'instancier com.google.inject.servlet.ManagedServletPipeline qui est une classe de paquetage privée utilisant un constructeur public. J'ai déjà vu ce problème avec Guice lorsque j'utilise des classes paquet-private, et la solution a toujours été de simplement changer la visibilité du constructeur de public à default. Le problème ici est que ManagedServletPipeline est une classe de framework et donc je n'ai pas vraiment accès pour la modifier. Je suppose que je fais quelque chose de mal puisque cela se manifeste dans les exemples les plus basiques.
Est-ce que quelqu'un sait comment je peux contourner ce problème?
La pile complète et les fichiers pertinents sont inclus ci-dessous. Pour info, j'essaye de lancer ceci sur Apache Tomcat v6.
