openapi spec returns schema of incorrect type

[spacether]

If additionalProperties exists in the fruit model, then
final Schema schema = openAPI.getComponents().getSchemas().get("fruit");
returns an instance of MapSchema.
Without additionalProperties, it returns the correct type of ComposedSchema.

incorrectly returns MapSchema as the type of the above schema instance for fruit.

Requested change:
When additionalProperties is included in a composed schema, please return an instance of ComposedSchema which includes additionalProperties info.
