How to solve occasional Apache Camel failures when reading from IBM MQ? - apache-kafka

Question

I have Apache Camel based simple POC app trying to pull messages from IBM MQ and post it to Apache kafka. I see the log file is continuously rolling with the below exception. I did some search on this issue with not much help.
I also found a fix was made in Apache NiFi project for the same issue. Not sure if the same fix needs to be applied in Apache Camel/Kafka project as well. Here is the JIRA URL.
https://issues.apache.org/jira/browse/NIFI-4976
The camel version used - 2.21.1
Here is the complete stacktrace,
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..
