    Description

      If we are executing the following code and there is a module.xml that contains a permission markup, we get an IllegalArgumentException: moduleLoader is null:

      Iterator<String> stringIterator = ml.iterateModules((String) null, true);
        while (stringIterator.hasNext()){
            ...
        }

      The exception is:

      Exception in thread "main" java.lang.IllegalArgumentException: moduleLoader is null

      It seems jboss modules is unable to parse a module.xml under those circustances and when we are iteraing over the available modules.

      Source of the problem could be LocalModuleFinder:299, where the moduleLoader argument for parseModuleXml() is explicitely set to null.
