Also, 

The reason this probably worked in Beta3 is because I don't think we enforced
modularity yet at that point.

Yeah, the confusing thing here is that even though SwitchYardFacet is in the same module
(different resource-root) as the Facet that is requesting it, it cannot find the class.
Does that sound possible? Is this maybe a problem with weld not scanning/loading
SwitchYardFacet for some reason?

    Stuart,

    The missing class is SwitchYardFacet.class.      The thing that I
    don't understand is that it is contained in one of the other
    resource roots, but not the one that makes this reference.    
    Shouldn't it be able to find it?

    The other strange thing is that this worked in Forge 1.0.0.Beta3.

    Actually looking at that stack trace I would say that
      the missing class is one of:

      {
          DependencyFacet.class, PackagingFacet.class,
          SwitchYardFacet.class }

      Based on the fact that it is dying inside parseClassArray(). 

      Are all these classes in the same module? An easy way to
        experiment is to set a breakpoint, and then in the watches
        window do

CamelFacet.class.getClassLoader().loadClass("com.blagh.DependencyFacet")
        and see which ones are not accessible.

          Hey Stuart, 

            I have a favor to ask regarding Weld/JBM. If you have a few
            seconds, could you take a look at something for me? The
            steps to reproduce this problem are in the issue (and this
            email thread,) but I'm pretty much at a loss to why this
            isn't working. We're getting that lovely
            sun.reflect.annotation.

              TypeNotPresentExceptionProxy again, this time on a class
              that is in a resource root of the same module, but doesn't
              seem to be found.

            I'd love to hear your thoughts.

                      Ok well, once I
                        turned on logging I was able to figure out the
                        root cause, but I don't know exactly why yet.
                        I'm assuming that the stack trace is fairly
                        obvious. The question is. "What is the correct
                        way to resolve it?"

                        Side note: I really need to add a logging toggle
                        in Forge itself, but it would need to go into
                        the launcher, just haven't gotten around to it
                        yet. Currently, one needs to edit the build to
                        enable logging *gulp* (Search for "LOGGING") in
                        the source and you'll see what I mean :/ That
                        might be my tomorrow (in addition to working on
                        this.) I'm going to be cutting a Beta5 very soon
                        because of some issues in the recent Beta4.

 I'm not exactly sure why this                              
      is happening. As long as the plugins
                                    are distributed as a single module,
                                    all resource-roots in that module
                                    should have classloader visibility
                                    between one another. They should
                                    also prefer their local classes over
                                    classes in other classloaders if
                                    there is duplication.
