The JMS 1.1 specification contains the following explanation of message priority.
JMS defines a ten-level priority value, with 0 as the lowest priority and 9 as the
highest. In addition, clients should consider priorities 0-4 as gradations of
normal priority and priorities 5-9 as gradations of expedited priority.
JMS does not require that a provider strictly implement priority ordering of
messages; however, it should do its best to deliver expedited messages ahead
of normal messages.
