Currently all class: JavaDelegates will be created via Class.newInstance.
But when using CDI or Spring we might use managed beans instead new instances.

By introducing an AtrifactFactory SPI which has a method to getInstance and destroyInstance we can switch out the default behaviour for utilizing the BeanManager if someone uses the cdi-engine and the BeanFactory in the Spring specific implementation.

Both impls might fall back to newInstance if there is no managed bean for this class.
