AMQP examples for Qpid Proton under https://github.com/apache/activemq-artemis/tree/master/examples/protocols/amqp have these two issues.

• The proton-cpp example uses the library qpid-cpp, not qpid-proton-cpp. It should be changed or renamed.
• The proton-ruby example is currently broken and won't start with recent Proton. Even if this was fixed, the example uses deprecated API. It should be updated.
• New major version of AMQP.netlite client was released, which is backwards incompatible. The current example is for the previous version.
