[forge-dev] Weird error again....

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.

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.

They should also prefer their local classes over classes in other classloaders if there is duplication.
