Maximum call stack size exceeded

Swagger that passes validation and also works in the 2.2.8 version of the UI causes the following error:

Resolver error
Maximum call stack size exceeded

Here is a sample swagger repro case:

The problem is related to the definition that represents a tree structure, it has an array property of itself.

Have the same issue with http://petstore.swagger.io/?url=https://raw.githubusercontent.com/oasis-tcs/odata-openapi/master/examples/example.openapi.json.

This file worked fine with Swagger UI version 3.0.4 and is now broken with version 3.0.6.

Have the same issue. Guys, can we force up it to p0? We have a broken documentation right now and it's very painful for us.

@seifer I suggest you downgrade for now then.

[seifer]

@webron Yeah, done it :) When will this issue fix?

[webron]

When we get around to it. We have limited resources. PRs are welcome.

The root cause is a model that has a $ref to itself. The example in the OP was direct, it may happen with an indirect cycle as well. Also note that swagger-editor has the same problem - would this imply this is in shared code (perhaps swagger-js)?
