> QueueEntries can hold Subscriptions which rejected them in memory after they are closed,
due to the implementation of the isRejectedBy() method. This is further compounded by the
Subscriptions having a reference to the channel/session they belong to, which in the case
of a 0-10 ServerSession can be an extremely heavy weight object in the wrong conditions. The
isRejectedBy() implementation should be updated to function without requiring a reference
to the Subscription itself, thus preventing the retention leak.
> I have had a simple patch for this for a while, its just waiting for QPID-3386 being
done (which it almost is, will get it committed shortly).
