Summary: camel-base-engine - AsyncProcessorAwaitManager: create
the latch only when the callback is still pending
Key: CAMEL-26473
URL: https://issues.apache.org/jira/browse/CAMEL-26473
Project: Camel
Issue Type: Sub-task
Reporter: Adriano Machado
Assignee: Adriano Machado
Fix For: 4.24.0
Tier 2 item of CAMEL\-25132. {{DefaultAsyncProcessorAwaitManager.process}}
allocates a {{CountDownLatch}} on every synchronous over asynchronous call,
which is every {{ProducerTemplate}} send and every
{{AsyncProcessorSupport.process\(Exchange\)}}. A temporary counter showed the
callback had already fired when {{process}} returned in 100% of the calls, for
routes with processors, sub routes, split, multicast, redelivery and seda, so
the latch was not waited on.
The latch can be created only when the callback has not fired yet when the
processor returns, with an atomic handshake for a callback arriving at that
moment. Waiting, the blocked exchanges view and forcing a blocked exchange to
complete keep working as they do.
