> 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.
