- Exception Summary
  Exception | Description
  --- | ---
  IgnoredPropertyException | Specialized `JsonMappingException` sub-class used to indicate case where an explicitly ignored property is encountered, and mapper is configured to consider this an error.
  InvalidDefinitionException | Intermediate exception type used as the base class for all `JsonMappingException`s that are due to problems with target type definition; usually a problem with annotations used on a class or its properties.
  InvalidFormatException | Specialized sub-class of `MismatchedInputException` that is used when the underlying problem appears to be that of bad formatting of a value to deserialize.
  InvalidNullException | Exception thrown if a `null` value is being encountered for a property designed as "fail on null" property (see `JsonSetter`).
  InvalidTypeIdException | Exception thrown when resolution of a type id fails.
  MismatchedInputException | General exception type used as the base class for all `JsonMappingException`s that are due to input not mapping to target definition; these are typically considered "client errors" since target type definition itself is not the root cause but mismatching input.
  PropertyBindingException | Base class for `JsonMappingException`s that are specifically related to problems related to binding an individual property.
  UnrecognizedPropertyException | Specialized `JsonMappingException` sub-class specifically used to indicate problems due to encountering a JSON property that could not be mapped to an Object property (via getter, constructor argument or field).
