The below example code describes my situation. I need to add the type information to the serialization of a class. I have other classes that extend this interface but that should not matter.
I included a zip of the example code that I have for producing the error.
What I get is
Caused by: com.fasterxml.jackson.core.JsonGenerationException: Can not
start an object, expecting field name (context: Object)
at com.fasterxml.jackson.core.JsonGenerator._reportError(
JsonGenerator.java:1961)

I am failing to find or discover what the error really is and why it is
trying to write a filed that I didn't specify as.
