Sergey Beryozkin commented on CXF-6564:
---------------------------------------
This is not handled by CXF JAXB DataBinding.
It is a JAXB issue only, perhaps you need to add the adapters. Not sure why it
worked earlier.
CXF 3.0.x depends on JAXB 2.1, 3.1.x - on 2.2.1. Perhaps it explains why...
As I said try adding the adapters and also investigate on JAXB forums.

> Project: CXF
> Issue Type: Bug
> Components: JAX-RS
> Affects Versions: 3.1.2
> Reporter: Abhishek Rawat
> Fix For: NeedMoreInfo

> I have this particular payload:
> @XmlRootElement(name = "data")
> @XmlAccessorType(XmlAccess.Field)
> public class ResponsePayload{
> @XmlElement(name = "messages")
> @Setter
> @Getter
> private List<Map.Entry<String,String> messages

> JAXB was working fine for converting the class to json payload with apache
> cxf 3.1.1.
> But with 3.1.2 it throws the following error:
> Caused by: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 1 counts
> of IllegalAnnotationExceptions
> java.util.Map$Entry is an interface, and JAXB can't handle interfaces.
