Because the message body reader knows the type it should instantiate,
it will be passed in as a parameter to the readFrom method:
https://jsr311.dev.java.net/nonav/javadoc/javax/ws/rs/ext/MessageBodyReader.html
#readFrom(java.lang.Class,%20java.lang.reflect.Type,
%20java.lang.annotation.Annotation[],%20javax.ws.rs.core.MediaType,
%20javax.ws.rs.core.MultivaluedMap,%20java.io.InputStream)
That type will be MyConverter.class.
