      Attached a maven project as a reproducer. Download it, unzip and execute:
      java -jar ./target/lib/jboss-modules-1.8.6.Final.jar -mp target/classes/modules local.tests.module

      IAE is thrown.
      If you comment the permission section in the module.xml, the project is executed without problems

      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:

      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.
