Thanks @dmiller and @robin for this! I was having a similar issue with some of my custom snaps.

import com.fasterxml.jackson.databind.ObjectMapper;

The org.codehaus.jackson-package version is from an older version of Jackson. The com.fasterxml.jackson-package version is the right one. See java - org.codehaus.jackson versus com.fasterxml.jackson.core - Stack Overflow for more.

The implementation that is injected is SnapObjectMapper, which extends com.fasterxml.jackson.databind.ObjectMapper. It enables some Jackson serialization features by default, as well as some custom serializers for Dates/Times/DateTimes.
