Piotr Klimczak updated AMQ-8299:
--------------------------------
Description:
The core principle of messaging system is that payload sent by producer is
received exactly same (unmodified) on consumer side.
However due to ActiveMQMapMessage using HashMap for map data, the order of
entries is not guaranteed effectively causing data corruption.
This is especially true when we are sending LinkedHashMap on producer side.
Then the consumer side will receive out of order data.
