unable to work with streams + Artemis large messages with AMQP factory

[Modanese, Riccardo]

Hello everyone,
     I’m working on supporting in a proper way the Artemis large messages 
through Camel streams.
>From the documentation it looks like this is supported only using AMQP or CORE 
>protocol (no JMS).
We use a custom factory since we need to set the connection client ID.

I set up Camel routes adding streamCache="true" to every route definition and 
camel context definition.
I also added the stream cache configuration to each Camel context:

<camel:streamCaching id="myCacheConfig" bufferSize="16384" enabled="true" 
spoolDirectory="/tmp/camel_cache" spoolThreshold="65536"/>

This configuration didn’t work using this connection factory:
        org.apache.qpid.jms.JmsConnectionFactory
with this url:
        public ServiceConnectionFactoryImpl(String host, int port, String 
username, String password, String clientId) {
           super(username, password, "amqp://" + host + ":" + port);
            ...
        }
It looks like, from my understanding, that this factory is creating a JMS 
connection even if I specify the AMQP protocol in the connection url.
But this works (connect and subscribe and receive messages from the broker) 
using an Artemis connector with only AMQP protocol set (is the AMQP protocol 
acceptor also supporting JMS?)

Anyway, changing the factory to use CORE protocol routes work fine with the 
Camel configuration I set.
        org.apache.activemq.artemis.jms.client.ActiveMQConnectionFactory
with this url
        public ServiceConnectionFactoryImpl(String host, int port, String 
username, String password, String clientId) {
            super("tcp://" + host + ":" + port, username, password);
            ...
        }

What I’m doing wrong?
How can I configure my factory to force AMQP protocol to be used (since it’ 
supported with streams and Artemis large messages)

Any suggestion is appreciated!
