Repeated declarations and deletions of the queue, broker's memory increased(NEVER decreased)

The more I run Java test code which is simply declare/delete queue and
check the queue existence by queuequery(please see atatched Java file), the more
C++ broker memory size increase(NEVER decrease).
Every times, the test code is successful.

In test code, it's repeated declarations and deletions of the queue 10,000 times.

Here is run summary.
A run represent one iteration through the whole test.
i.e. each run has done declarations and deletions of the queue 10,000 times and totally 100,000 times in this case.
