What can cause this exception in apache camel

Question

I get this exception at runtime:

And then the rest of the stack trace.

What could cause this exception, knowing that it was working before?

Answer 1

java.lang.IllegalArgumentException: connectionFactory must be specified

You should check your camel JMS component configuration that the connection factory is set to a correct factory.
