In looking at the 0.95 Java C&I spec (and it looks to be done the same
way in the draft 1.0 spec) I see that it should be possible to have
multiple references collected up in a list using an annotation such as
the following:
@Reference(name="helloService", required=true)
public List<HelloService> helloServices;
However attempting this gives me the following error:
org.apache.tuscany.spi.builder.BuilderConfigException: Incompatible

Should this be working in M2? Is this broken or is multiplicity per
the spec not supported at this time?
