Decide on use of String or AMQShortString in broker code base
-------------------------------------------------------------
Key: QPID-2578
URL: https://issues.apache.org/jira/browse/QPID-2578
Project: Qpid
Issue Type: Improvement
Components: Java Broker
Affects Versions: 0.6
Reporter: Martin Ritchie
Currently we have no clear guidance on when String or AMQShortString should be
used. As a result things like queue recovery during start up does a large
number of new AMQShortString() then toString() then new AMQShortString() as the
value is passed through the various constructors.
For an example follow what happens to 'owner' in the queue recovery path from
loadQueues in DerbyMessageStore.
We should ensure we minimise the transformations that we are doing.
Whilst this is not on the message delivery path the numerous transformations
that owner goes through is probably not an isolated occurrence.
