This is a great patch! Thank you a lot for the investigation and the fix.

Can you submit it also against swagger-api/swagger-parser?

We are not really using this fork for now.

[jmini]

Or if you agree I will present it in the official project after having added a unit test for your use case.

Hi @jmini, I just opened the PR there: swagger-api#753
Please feel free to add a test to that branch, or to pick the commit into your own branch.

[jmini]

I do not have the right to push anything on your no-info-block-oas3 branch, but I have created 9d0094a on top of https://github.com/bmordue/swagger-parser/commit/4a8e21846720edce0b7246ebc08182669998e242

Can you:

1. give me push right to your branch (I am not maintainer of the other project)
2. rebase (fast-forward) your no-info-block-oas3 on top of OpenAPITools/no-info-block-oas3

If you edit this PR, are you able to change the branches to:

@bmordue wants to merge 1 commit into OpenAPITools:2.0-OpenAPITools from bmordue:no-info-block-oas3

Current is:

@bmordue wants to merge 1 commit into OpenAPITools:2.0-OpenAPITools from bmordue:no-info-block

Maybe this will give me write right as maintainer of this project.

@jmini Do we still want this PR open, or shall I close it in favour of this one: swagger-api#753 ?

[jmini]

Leave it open, we like to have the commits our community is interested in our 2.0-OpenAPITools branch. Just in case we need to release it ourself.
