From af2e4018c92b0fb311f60dfe507335b12e2935a4 Mon Sep 17 00:00:00 2001 From: Jim Hahn Date: Fri, 13 Sep 2019 12:14:25 -0400 Subject: Extract YamlJsonTranslator from StandardYamlCoder Refactored StandardYamlCoder, extracting a new class, YamlJsonTranslator, from it. This facilitates performing yaml translation when not using a standard "gson" coder. Added YamlJacksonHandler which supports YAML translation layered on top of a JacksonHandler instead of a GsonMessageBodyHandler. Also added junit tests to complete coverage of StandardCoder. Also added public APPLICATION_YAML to YamlMessageBodyHandler.
