QPID-7827: Delegate the creation of UUIDs to factory to avoid proliferation of
UUID instances representing the same underlying UUID.
Cherry picked from 2ddbca0b16e47b18f24beaa1f4fa88d594a25618. Manually resolved
conflicts and backported CachingUUIDFactory to JDK 1.7 (#putIfAbsent).
> Recoverers allocate separate queue UUID for each recovered message instance

> Key: QPID-7827
> URL: https://issues.apache.org/jira/browse/QPID-7827
> Project: Qpid
> Issue Type: Improvement
> Components: Java Broker
> Reporter: Keith Wall
> Assignee: Keith Wall
> Fix For: qpid-java-broker-7.0.0, qpid-java-6.1.4, qpid-java-6.0.8
>
>
> The asynchronous and synchronous recoverers allocate a new queue UUIDfor
> each and every message instance. This means that the heap representation
> for n recovered messages is larger (by sixteen bytes) than the representation
> required if the same messages had arrived over the wire. The problem exists
> for both JDBC and BDB recoverers.
