Inconsistent content encodings allowed #1711
Description
From the OpenAPI spec for MediaType:
encoding: A map between a property name and its encoding information. The key, being the property name, MUST exist in the schema as a property.
It is an error if the encoding map contains a key that is not defined as a property name in the content (object) schema. But this error is not recognized. The following test fails because it doesn't report the encoding for non-existent property "Z" as an error.
@Test

String json =
