Spring boot messaging Failed to serialize object caused by jaeger #320
Description
I spent now 2 days trying to figure out how to solve this but I am out of luck..
We added java-spring-cloud-starter version 0.5.9 to our spring boot application v2.1.3
We have some DomainEvents that we need to serialize, we use MessageChannel of spring boot framework.
which creates a GenericMessage
https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/messaging/Message.html
Here is a snippet from our implementation

What I found out is that jaeger is adding something to this GenericMessage (see the stack trace below)
I don't know how to solve this issue and for me it looks like a bug...can anyone help me out? I could find anything in the interwebs.
