Apache Camel：无法为端点创建生产者，原因：ArrayIndexOutOfBoundsException

Question

I'm routing ActiveMQ messages using Apache Camel.

Some times! I get this exception in my router:

[ERROR] DefaultErrorHandler(Camel (camel-1) thread #11 - Threads):161 - Failed delivery for (MessageId: queue_Q. ... on ExchangeId: ...). Exhausted after delivery attempt: 1 caught: org.apache.camel.FailedToCreateProducerException: Failed to create Producer for endpoint: Endpoint[activemq2://queue:Q.D_Test]. Reason: java.lang.ArrayIndexOutOfBoundsException: 22. Processed by failure processor: FatalFallbackErrorHandler[Channel[sendTo(Endpoint[activemqException://queue:Q.Exception_Test])]]

and the stacktrace:

org.apache.camel.FailedToCreateProducerException: Failed to create Producer for endpoint: Endpoint[activemq2://queue:Q.D_Test]. Reason: java.lang.ArrayIndexOutOfBoundsException: 22

Answer 1

Can you upgrade your camel version to 2.12.2? I just check out the code change, it should be fix in CAMEL-6941 .
