libmsgpack-java 0.9.6-1 (armhf binary) in ubuntu oracular

 MessagePack is a binary serialization format. For example, a small integer can
 be encoded in a single byte, and short strings only need a single byte prefix
 + the original byte array. MessagePack implementation is already available in
 various languages and works as a universal data format.

 msgpack-java supports serialization and deserialization of Java objects through
 jackson-databind.
