Как решить случайные сбои Apache Camel при чтении из IBM MQ?

/ 15 мая 2018

У меня простое POC-приложение на основе Apache Camel , которое пытается извлечь сообщения из IBM MQ и опубликовать его на Apache kafka . Я вижу, что файл журнала постоянно катится, за исключением следующего. Я немного искал по этой проблеме, но не очень помог.

Я также обнаружил, что в проекте Apache NiFi было исправлено то же самое. Не уверен, нужно ли применять такое же исправление в проекте Apache Camel / Kafka. Вот URL JIRA.

https://issues.apache.org/jira/browse/NIFI-4976

Используемая версия верблюда - 2.21.1

Вот полная трассировка стека, 

org.apache.camel.RuntimeCamelException: Failed to extract body due to: com.ibm.msg.client.jms.DetailedJMSException: JMSCMQ1049: The character set '1208(UTF-8) Unmappable Action: REPORT Unmappable Replacement: 63' cannot convert some or all of the string '[B@b1beb88'
An attempt was made to send or receive string data using a character set not capable of translating the strings content.
Only encode a message using a character set known to be appropriate for the string data being transmitted..
