JBoss eap 6/as 7 class 加载程序：如何修复 LinkageError
JBoss eap 6/as 7 class loader: how to fix LinkageError
我正在尝试在 jboss eap 6 上部署我的 seam 2.2.2 应用程序。
1) 我的应用程序需要lucene-core.jar 所以我必须把它打包在我的耳朵里
2) Hibernate-search模块依赖lucene-core模块加载。
然后失败：

这似乎是不同 class 加载器的问题，但由于我是 jboss 模块机制的新手，我不知道如何解决这个问题。有什么建议吗？
我通过将 lucene-core 模块定义为全局模块来解决这个问题。
