/**
 * Enables Mule annotation processing so that annotated objects registered with the
 * Mule registry will automatically be configured. This helper also enables JSR-330
 * injection annotations javax.inject.Inject and
 * javax.inject.Named.
 * 
 * Internal Implementation note: We could have used a 'registry-bootstrap.properties'
 * file to load the objects necessary to enable annotations however, that method
 * would not allow the annotation processors to be easily overridden when using other
 * platforms such as Google App Engine.

 * @since 3.0
