Though it seems like sort of bug, but would like to confirm if somebody came across this situation in Apache Camel version 2.18.1.redhat-000021, No matter what's the value for maximumRedeliveries, route on failure is only being tried twice.
errorHandler(deadLetterChannel("amq:queue:ENTDLQ").maximumRedeliveries(5).useOriginalMessage()
.onRedelivery((Exchange e) ->{
log.info("--------------- Re-delivered..." + e.getIn().getHeaders());
})
.redeliveryDelay(2000).retryAttemptedLogLevel(LoggingLevel.WARN));
Logs below
On delivery attempt: 0 caught: org.apache.camel.http.common.HttpOperationFailedException: HTTP operation failed invoking http://0.0.0.0:0/someservice with statusCode: 404
--------------- Re-delivered...{CamelJmsDeliveryMode=2, CamelRedelivered=true, CamelRedeliveryCounter=1, CamelRedeliveryMaxCounter=5, JMSCorrelationID=Camel-ID-Shoaibs-MacBook-Pro-local-56371-1518552634307-0-6}
