Description

The jersey2 library fails deserialization when the input data contains additional (undeclared) properties. For example, suppose the input data is the following JSON document:

{
      "Name": "Bob",
      "CreateTime": "2020-04-13T21:57:56.552Z",
      "UserUniqueIdentifier": "2aff0200-3d2e-4ba3-823d-c9ea8877556d"
}

The schema explicitly declares Name and CreateTime but not UserUniqueIdentifier:

When the jersey2 library attempts to deserialize the payload, an error occurs:

INFO: Input data does not match schema 'XYZ'
com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException:
Unrecognized field "UserUniqueIdentifier" (class XYZ),
not marked as ignorable (31 known properties: ""CreateTime", "Name", ...])
 at [Source: UNKNOWN; line: -1, column: -1]
(through reference chain: XYZ["Results"]->java.util.ArrayList[0]->XYZ["UserUniqueIdentifier"])
