-----------------------------------
Summary: ActiveMQMapMessage should use LinkedHashMap to preserve
original order
Key: AMQ-8299
URL: https://issues.apache.org/jira/browse/AMQ-8299
Project: ActiveMQ
Issue Type: Bug
Components: JMS client
Affects Versions: 5.16.2
Reporter: Piotr Klimczak
The core principle of messaging system should be that payload sent by produced
is received exactly same (unmodified) on consumer side.
However due to ActiveMQMapMessage using HashMap for map data, the order of
entries is not guaranteed.
This is especially true when we are sending LinkedHashMap on produced side.
Then the consumer side will receive out of order data.
