/**
* A Jackson 2.x codec for encoding and decoding SockJS messages.
*
* It customizes Jackson's default properties with the following ones:
*
* - {@link MapperFeature#DEFAULT_VIEW_INCLUSION} is disabled
* - {@link DeserializationFeature#FAIL_ON_UNKNOWN_PROPERTIES} is disabled
*
*
* Note that Jackson's JSR-310 and Joda-Time support modules will be registered automatically
* when available (and when Java 8 and Joda-Time themselves are available, respectively).
