Hi,
There is a class cast exception raised when the ServiceProxyWrapper
object is cast into A.

Hi,
when defining a service property with a reference as a value, the property is
assigned with a ServiceProxyWrapper (inner class of ReferenceRecipe).
Here is the way it is defined:
<service ref="..." interface="...">
<service-properties>
<entry key="Property1">
<ref component-id="serviceRef"/>
</entry>
</service-properties>
</service>
<reference id="serviceRef" interface="A" />
I would have expected the service property "Property1" to be assigned with an instance of
"A" instead of a ServiceProxyWrapper. However I could get the instance of "A" by calling
the method 'convert' and passing a ReifiedType.
I would assume that the actual ServiceProxyWrapper object passed in actually *is* and
instance of A as in "xyz instanceof A". Otherwise it would be a violation of
the spec etc. The actual class of the supplied object is none of the consumer's business.
There is no need to unwrap IMHO.

I would like to know if defining such a service property (containing a<ref>) is
correct according to Blueprint specification and Aries implementation?
I would also like to know why the 'convert' has to be done explicitly?
Thank you.
