ActiveMQ Classic JMS 2.0 no support for PooledConnectionFactory

JMS Support 2.0 works fine with AMQ Classic 6.x, but if I use activemq-pool

<dependency>
   <groupId>org.apache.activemq</groupId>
   <artifactId>activemq-pool</artifactId>
   <version>6.1.3</version>
</dependency>

I get

java.lang.UnsupportedOperationException: createContext() is not supported
    at org.apache.activemq.jms.pool.PooledConnectionFactory.createContext(PooledConnectionFactory.java:280)

So, JMS 2.0 support seems not to be provided here (although the correct transient amq-client dependency is included).

Any reasons for that?

What you're seeing is expected. I recommend you use this pool which is based on the ActiveMQ Classic code-base, but has full support for JMS 2.

That said, it's worth noting that no version of the JMS client implementation shipped with ActiveMQ Classic fully supports JMS 2, even in the latest 6.x release. It still lacks support for the following JMS 2 features & methods:

• Methods to Receive a Message Body Directly
  • JMSConsumer.receiveBody(Class)
  • JMSConsumer.receiveBody(Class, long)
  • JMSConsumer.receiveBodyNoWait(Class)
• Delivery delay
  • JMSProducer.setDeliveryDelay(long)
  • JMSProducer.getDeliveryDelay()
  • MessageProducer.setDeliveryDelay(long)
  • MessageProducer.getDeliveryDelay()
• Sending Messages Asynchronously
  • JMSProducer.setAsync(CompletionListener)
  • JMSProducer.getAsync()
  • MessageProducer.send(Destination, Message, CompletionListener)
  • MessageProducer.send(Destination, Message, int, int, long, CompletionListener)
  • MessageProducer.send(Message, CompletionListener)
  • MessageProducer.send(Message, int, int, long, CompletionListener)
• Shared Topic Subscriptions
  • Session.createSharedConsumer(Topic, String)
  • Session.createSharedConsumer(Topic, String, String)
  • Session.createSharedDurableConsumer(Topic, String)
  • Session.createSharedDurableConsumer(Topic, String, String)
  • JMSContext.createSharedConsumer(Topic, String)
  • JMSContext.createSharedConsumer(Topic, String, String)
  • JMSContext.createSharedDurableConsumer(Topic, String)
  • JMSContext.createSharedDurableConsumer(Topic, String, String)

If you want a full JMS 2 implementation I recommend ActiveMQ Artemis.
