The only downsides I would see (and also why I opted for subclasses instead of a static factory) is that it would make debugging CL leaks more difficult if all CLs were to just be ComponentClassLoaders. (Because you cant filter out plugin loaders for example). So maybe it should indeed be an abstract class. -- This is an automated message from the Apache Git Service.
