1.2. Key Migration Issues

activemq-core component
Copy link

In Apache ActiveMQ version 5.8, the activemq-core component is no longer available. It has been split up into the following components: 
activemq-client
activemq-broker
activemq-jdbc-store
activemq-kahadb-store
activemq-leveldb-store
Copy to Clipboard Toggle word wrap
This enables your applications to be more lightweight and modular. For example, a Java client application now requires only the activemq-client JAR, which is much smaller than the old activemq-core JAR.
If you are using the Apache Maven build system, you must replace the activemq-core artifact by either the activemq-broker artifact or the activemq-client artifact.
Note
The activemq-all component (which encapsulates the whole ActiveMQ runtime) is still available.

JMX MBeans renamed
Copy link

The JMX MBeans exposed by ActiveMQ have been refactored to conform to a hierarchical naming structure. If you have any application code that accesses JMX MBeans, you must re-write your code to use the new ObjectName values. All MBeans now share the type=Broker attribute (where type now starts with a lowercase t). The mapping from old to new ObjectName values is shown in the following table:
Expand
Object TypeOld ObjectNameNew ObjectNamed
BrokerType=Brokertype=Broker
DestinationType=Queue|Topic,Destination=<destination identifier>type=Broker,destinationType=Queue|Topic,destinationName=<destination identifier>
