我正在使用Jboss EAP 7.1，当我尝试从ServiceModuleLoader中转储AllModuleInformation时，出现了空指针异常，但是我可以看到LocalModuleLoader的结果。在下面附加堆栈跟踪。
基本上，我正在尝试查看我的war文件的所有已加载资源。我真的不确定空指针异常的原因是什么。其他所有操作，例如dumpModuleInformation，getDependencies，getModuleDescription，getModulesPathInfo，refreshResourceLoaders，relink和unLoadModule都抛出IllegalArguementException：模块规范为null。只有queryLoadedModuleNames返回我的战争文件名。应用程序运行正常，没有任何问题。 Jconsole也抛出相同的异常。我需要找到一种方法来查看我的war文件中所有已加载的jar。独立服务器托管有多个war文件，因此计划编写一个JMX程序来获取我所有战争/耳朵的已加载依赖关系。你们能帮我吗
