Resolves #3624 for 2.x
The earlier handling for
additionalProperties
in OpenAPI was flawed. TheadditionalProperties
setting in an OpenAPI document can be either boolean or a schema.The MP OpenAPI
Schema
class exposes additional properties as getters and setters foradditionalProperties
(now deprecated),additionalPropertiesBoolean
, andadditionalPropertiesSchema
.This situation presents some challenges for serializing and deserializing OpenAPI documents and the earlier code did not do this correctly through its customizations to the SnakeYAML parsing and rendering.
This PR fixes those problems and adds more tests for both input and output.
