/**
 * JSON content type provider automatically configured to use both Jackson
 * and JAXB annotations (in that order of priority). Otherwise functionally
 * same as {@link JacksonJsonProvider}.
 *
 * Typical usage pattern is to just instantiate instance of this
 * provider for JAX-RS and use as is: this will use both Jackson and
 * JAXB annotations (with Jackson annotations having priority).
 *
 * Note: class annotations are duplicated from super class, since it
 * is not clear whether JAX-RS implementations are required to
 * check settings of super-classes. It is important to keep annotations
 * in sync if changed.
