Hello,
I'm not atmosphere expert, but I think important here are following lines:
SEVERE: A message body writer for Java class A, and Java type class
A, and MIME
media type text/html was not found
class A is @XmlRootElement annotated and Jersey provides marshalling (serializing) for it BUT only for certain media types, like application/xml text/xml and */*+xml. Try to use anything from that list and it should disappear.
Regards,
Pavel
