Description
Currently Jackson object mapper will happily deserialize an object with bogus union types. This is desirable in certain cases as it allows for additive changes. However, on the server side quite often we want to discard such objects.

Research direction
Start by locating the Jackson object-mapper deserialization configuration and the code handling union types. Reproduce deserialization of an object containing a bogus union type, then determine how strict rejection should be enabled without changing the existing additive-compatible behavior. Done means the strict behavior is configurable and covered by tests.
