Hi,
I verified that it works. See attached for a simple maven project.
Note that what can be injected at the construction of an Application
instance is limited. Because the application can itself define further
stuff to be injected or provider components the infrastructure for
most providers will be initialized after the instantiation of the
Application instance.
