----------------------------------------
Summary: camel-spring-rabbitmq - Effective default of replyTimeout
is 5000 millis instead of the documented 30000
Key: CAMEL-24068
URL: https://issues.apache.org/jira/browse/CAMEL-24068
Project: Camel
Issue Type: Bug
Components: camel-spring-rabbitmq
Affects Versions: 4.22.0
Reporter: Federico Mariani
The endpoint option {{replyTimeout}} is documented with default 30000 millis
(30 seconds) and the field in {{SpringRabbitMQEndpoint}} is initialized
accordingly:
{code:java}
@UriParam(label = "producer", javaType = "java.time.Duration", defaultValue =
"30000", ...)
private long replyTimeout = 30000;
{code}
However {{SpringRabbitMQComponent}} has its own {{replyTimeout}} option with
default 5000, and {{createEndpoint()}} unconditionally overrides the endpoint
value with it:
{code:java}
endpoint.setReplyTimeout(replyTimeout); // component field defaults to 5000
{code}
Since endpoints are always created through the component, the effective default
for request/reply (InOut) messaging is 5 seconds, contradicting the endpoint
documentation and the generated catalog. Users relying on the documented 30
seconds get a {{TimeoutException}} after 5 seconds.
Attached reproducer fails on current main:
{noformat}
replyTimeout should default to 30000 millis as documented on the endpoint
option ==> expected: <30000> but was: <5000>
{noformat}
Fix requires a decision on which default is intended: align the component
default (and its docs, currently claiming 5 seconds) to 30000, or fix the
endpoint annotation/docs to 5000. All other options duplicated on component and
endpoint level have matching defaults; {{replyTimeout}} is the only mismatch.
