QPID-4659 : [Java Broker] preliminary refactoring in preparation for pluggable protocols
> [Java Broker] Refactor broker to separate protocol independent from protocol specific classes
> ---------------------------------------------------------------------------------------------

> Key: QPID-4659
> URL: https://issues.apache.org/jira/browse/QPID-4659
> Project: Qpid
> Issue Type: Improvement
> Components: Java Broker
> Reporter: Rob Godfrey
> Assignee: Rob Godfrey
>
> The Java Broker currently supports all versions of the AMQP protocol from 0-8 to 1.0, however the current structure of the code within the broker makes it hard to distinguish between code which is specific to a version of the protocol and code which is common across all protocols.
> By refactoring we can separate the protocol dependent and independent parts and allow for the possibility of separating out the different protocol implementations into independently loadable libraries.
> Fundamentally the refactoring takes the form of moving protocol specific classes into org.apache.qpid.server.protocol.v{0-8,0-10,1-0} and sub-packages and using the QpidClassLoader to load the protocol implementations (there are three separate implementations to load - the protocol delegate creators that interface to the IO code; the MessageMetaDataTypes used to (de)serialize the message data to stores; and MessageConverters used to convert between message formats and allow 0-8 messages to be received by 1-0 consumers.
