Couldn't find a forum dedicated to jboss-modules, so I'll try here.

I'm trying to figure out if I can tell jboss-modules that some portions of the resources are "module-internal", i.e. that they cannot be accessed from any other module, not even the modules that has the target module as a direct dependency. So I tried experimenting with the module global <exports> directive. I have an "application" module like so:

<module xmlns="urn:jboss:module:1.3" name="x.app">
   <main-class name="xyzzy.app.Main" />
   <resources>
      <resource-root path="x-app-1.0.jar" />
   </resources>
   <dependencies>
      <module name="x.alpha" services="import"> </module>
   </dependencies>
</module>

and a the x-alpha module:

<module xmlns="urn:jboss:module:1.3" name="x.alpha">
   <exports>
      <include path="xyzzy/**" />
      <exclude path="org/reflections/**"/>
   </exports>
   <resources>
      <resource-root path="public/x-alpha-1.0.jar" />
      <resource-root path="private/reflections-0.9.10.jar" />
   </resources>
</module>

Then I try loading the class org.reflections.Reflections from the Main class

            Class<?> c = Class.forName("org.reflections.Reflections", true, Main.class.getClassLoader());

Based on exclude pattern, my guess is that it should fail, but it works. Do the exports directive have any effect at all? Well, if I put a top level wildcard in the exclude directive

   <exports>
      <include path="xyzzy/**" />
      <exclude path="*"/>
   </exports>

then loading fails, but then I cannot use any of the "public" classes.

Is this module global directive supposed to work the way I think, or am I using something unsupported/undocumented?

UPDATE

After some more experiments, setting the exports directive to

   <exports>
      <include path="xyzzy/**" />
      <exclude path="org/**"/>
   </exports>

yields the expected result, i.e. that

            Class<?> c = Class.forName("org.reflections.Reflections", true, Main.class.getClassLoader());

fails. Testing GlobPathFilter from master, though, suggest that something else is going on:

        assertTrue(new GlobPathFilter("org/**").accept("org/reflections/Reflections"));
        assertTrue(new GlobPathFilter("org/reflections/**").accept("org/reflections/Reflections"));

Both assertions succeeds.
