v3.25.3 breaking on definition containing property "entries"

[jgdiva]

Hallo,

with version v3.25.3 our API-definition is breaking. I did some line-by-line copy-and-pasting, and found out, that it always breaks whenever a definition contains a property named "entries". The error message is not that helpful:

Unable to render this definition
The provided definition does not specify a valid version field.

Please indicate a valid Swagger or OpenAPI version field. Supported version fields are swagger: "2.0" and those that match openapi: 3.0.n (for example, openapi: 3.0.0).

We are using "swagger: '2.0'"

Example of a breaking definition:

definitions:
...
ExampleWsDTO:
type: object
properties:
exampleproperty:
type: number
format: double
entries:
type: array
items:
$ref: '#/definitions/AnotherWsDTO'
anotherproperty:
$ref: '#/definitions/AnotherWsDTO'
...

When I remove the "entries" property, everything works fine. But I cannot actually remove or rename them in our definition.

With v.3.25.2, everything still works fine.

Can you have a look at this, please?

Thank you!
