Parsing of boolean `additonalProperties` inconsistent with OpenAPI 3.0.0 specification

I’m used to setting "additionalProperties": false from JsonSchema, hence did so in an OpenAPI 3.0.0 file, especially as it’s allowed by the specification.

Using version 2.0.0-SNAPSHOT of swagger-parser-v3 as found on oss.sonatype.org for OpenAPI file validation, I get a parse result message saying that additonalProperties is not of type object.

I’m aware of issue #366, but I think either

• the parser should accept boolean values for additionalProperties as well or
• it must be clearly stated in the specification if the parser is supposed to frown upon such values.

In addition, the message is a bit misleading because it is reported only once and only for the top level of the object definiton, even though there were several occurences of "additonalProperties": false on deeper levels of this definition. Providing a more precise location would have helped a lot with debugging this issue.

There’s a chance to get this fix on upstream before end January? 😄

Sorry about this - just got lost in the mass emails. We’ll try to take a look shortly.
