I have a package and in that controller's on_start method I reference an attribute Controller that is also part of my package. Everything works great in versions up to 5.7.4.3b. However, when I update to 5.7.5R2 it seems that when I call my attribute controller, I receive an error that the class can not be found. Again this is weird because it works in 5.7.4.3b.

Has something changed in the way autoloading is done? Is there any reason why referencing the attribute controller in the package's on_start would all of the sudden result in an exception?
