First time I’m hearing about this library. Could be useful for us in some places.
See 
http://juneau.apache.org/#documentation.html
<http://juneau.apache.org/#documentation.html>
Seems pretty feature rich.
• A universal toolkit for marshalling POJOs to a wide variety of content types using a
common framework.
• A universal REST server API for creating Swagger-based self-documenting REST interfaces
using POJOs, simply deployed as one or more top-level servlets in any Servlet 3.1 or above
container.
• A universal REST client API for interacting with Juneau or 3rd-party REST interfaces
using POJOs and proxy interfaces.
…
Serializers and parsers for:
        • JSON
        • XML
        • HTML
        • UON
        • URL-Encoding
        • MessagePack
        • SOAP/XML
        • CSV
        • BSON (coming soon)
        • YAML (coming soon)
        • Protobuf (coming soon)
Serializers and parsers for:
        • RDF/XML
        • RDF/XML-Abbrev
        • N-Triple
        • Turtle
        • N3
Anyone heard about it?
Thanks
