The current CDI integration does not cover all use cases using annotations since it persist the Iterables and Maps fields from the root class.

This improved integration collects the changed objects (objects marked as dirty) using a fluent API and those are stored at the end of the method (or the JAX-RS request)

public interface DirtyMarker {
    <T> T mark(T instance);
}

This integrations allows to clearly indicate what is changed and stores the changes in an synchronous way (synchronous is also possible through the annotation or configuration).
