      public final class FailingSerializer
      extends SerializerBase<Object>

  Special bogus "serializer" that will throw `JsonGenerationException` if its `serialize(java.lang.Object, org.codehaus.jackson.JsonGenerator, org.codehaus.jackson.map.SerializerProvider)` gets invoked. Most commonly registered as handler for unknown types, as well as for catching unintended usage (like trying to use null as Map/Object key).
