Paul McCulloch created CAMEL-7658:
-------------------------------------
Summary: Out of order processing of ActiveMQ queue with a single
consumer with CACHE_NONE
Key: CAMEL-7658
URL: https://issues.apache.org/jira/browse/CAMEL-7658
Project: Camel
Issue Type: Bug
Components: camel-activemq, camel-jms
Affects Versions: 2.13.2
Environment: Windows 7 x64. Java 7 & 8
Reporter: Paul McCulloch
Messages are occasionally consumed out of order when the JMS or ActiveMQ
component has a cache level name of CACHE_NONE or CACHE_SESSION.
The out of order message id is related to the previous message. For example:
messages received are:
02885-DESKTOP-60405-1407148471972-3:1:2:1:315
02885-DESKTOP-60405-1407148471972-3:1:2:1:1316
02885-DESKTOP-60405-1407148471972-3:1:2:1:316
Attempts to debug cause the issue not to occur - perhaps some sort of race
condition.
Test case attached. An equivalent test with plain Spring JMS, consuming via
DMLC passes.
