@mflorczak Hi! Could you add more information like which template do you want to use?

Have in mind that some templates doesn't support specification with the circular references.

EDIT: Could you also add the given spec with circular refs as plain text in the comment, not as images?

Currently we support the circular refs in the spec, but not in every places (more info here). Generator can parse/validate your spec and pass it to the template. The given error is throw by this line https://github.com/asyncapi/java-spring-template/blob/master/filters/all.js#L101 Native JSON. stringify function doesn't support the circular refs, so it's not a problem with generator, but it's related with template itself. I will close the issue, and please continue the discussion here.

Also please don't cut the error, because this line:

is most important :P
