the 0-10 Java client should use AcquireMode=PRE_ACQUIRED when using selectors
on a Queue destination and server-side selectors are in use

Key: QPID-3831
URL: https://issues.apache.org/jira/browse/QPID-3831
Project: Qpid
Issue Type: Improvement
Components: Java Client
Affects Versions: 0.14
Reporter: Robbie Gemmell
Assignee: Robbie Gemmell
Fix For: 0.15
When the 0-10 Java client is using selectors on a Queue destination and
server-side selectors are available (i.e its connected to the Java broker), it
should make use of AcquireMode=PRE_ACQUIRED instead of NOT_ACQUIRED in order to
take full performance advantage of the broker having pre-evaluated the selector
before sending it to the client. Currently, the client uses its awareness of
the server-side selector only to stop itself evaluating the selector a second
time (as the server already did it) when infact it should also use this
awareness to request messages be PRE_ACQUIRED.
