The integration of Artemis 1.4 introduced TCK failures on October 21 which analysis traced to the dependency of 1.4 on the org.apache.johnzon project. jperkins-rhn was able to make a fix[1] which looked like it would resolve the TCK problems, but it's unclear whether this will have negative effects. Also, the server side module tree does not include johnzon, and we're not sure if that was intentional.
So this task is for the expert to look into this and do whatever needs doing.
