-------------------------------------
Summary: camel-jms: Make ThreadPoolTaskExecutor the default Task
Executor
Key: CAMEL-5974
URL: https://issues.apache.org/jira/browse/CAMEL-5974
Project: Camel
Issue Type: Improvement
Components: camel-jms
Reporter: Raul Kripalani
Assignee: Raul Kripalani
Fix For: 2.9.6, 2.10.4, 2.11.0
{{DefaultJmsMessageListenerContainer}} uses
{{org.springframework.core.task.SimpleAsyncTaskExecutor}} as the default task
executor.
This causes a lot of thread thrash when setting a positive
idleTaskExecutionLimit. New threads are created every time the consumers are
refreshed, i.e. closed down and started again to keep the minimum number of
them around (= concurrentConsumers).
Replace with
{{org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor}} instead,
with the following config:
* corePoolSize = concurrentConsumers
* maxPoolSize = maxConcurrentConsumers
