>
> The value of {{delivery-count}} is conceptually unbounded but it is encoded
> as a 32-bit
> integer that wraps around and compares according to RFC-1982 serial number
> arithmetic. Broker-J does not handle the case of "negative credit" on a link
> correctly. For example, if deliver count is {{-1}} and credit is {{1}}, then
> limit would calculate as {{0}} and broker would stop sending messages
