Luciano Resende commented on TUSCANY-3543:
------------------------------------------
A workaround for this issue is to remove the name from one of the bindings to
make it the default one, or to specify component/service/binding on the
getService call.
> Creating selfReference when multiple bindings are available cause NPE
