[weld-dev] Question regarding behavior of Decorated dependent scoped beans

While verifying the behavior of decorated dependent scoped beans on
OpenWebBeans, Gurkan mentioned that he observed the same behavior on WELD.
While verifying myself I noticed two behaviors that seem to conflict with
the spec.

1) Non-normal scoped beans don't have any restrictions on public fields.  A
quick test showed that changes made to public fields directly are not
reflected when a call to a getter method that returns that value of the
public field is made.  Presumably this is because there is an proxy like
object in the middle.

For example

@Inject MyBean myBean;

myBean.number = 7;
myBean.getNumber(); //would return the default value for number and not 7
which it was just set to.

2) Non-normal scoped beans don't require a public no-args constructor.  If
the dependent scoped bean instead had a constructor annotated with @Inject
(as per 3.1.1), an InstantiationException was thrown.

Are these expected restrictions once that dependent scoped bean is
Decorated?

Sincerely,

Joe
