A client tries to create two links with the same name over the same connection/session. Spec section 2.6.1 suggests that the first link is closed with status 'stolen' and the second link is created.
Currently the second link attach is ignored . The client attach goes into the broker and no attach or error comes out. The same behavior happens to qpidd and to activemq 5.11 brokers.
A trace is available here:
 The client link state is half-half-attached.
