Component Utilities

With JSR 250 (commons-annotations) it is very easy to write components and therefore component-oriented applications.
This package provides some common runtime exceptions for typical errors of components (or whatever you call it).
Additionally InitializationState can be used to implement a component that requires strict initialization and wants to ensure that some methods have to be called before and others after initialization.
