That makes sense to me—I have just inlined the one use case.

> In some setups, there could be a few hundred thousand queues that are created
> due to many consumers that are connecting. However, most of these are empty
> and stay empty for the entire day since there aren't necessarily messages to
> be sent.
> The 8K {{intermediateMessageReferences}} instantiates an 64KB buffer
> ({{Object[]}}). This means we have large allocation and live heap that
> ultimately remains empty for almost the entire day.
> It would be quite nice if we could configure this initial size.
