Describe the bug you're encountering

To reproduce...

Steps to reproduce the behavior:

1. import file (Example Swagger ver2.0 definition)
2. Go to 'toolbar'
3. Click on 'Edit' > 'convert to OpenAPI 3'

Expected behavior

Now

           default: '["new","investigating","ongoing"]'  # Converted default value is not of type `array`

Correct output

            default:
              - new
              - investigating
              - ongoing

Additional context or thoughts

It would be more appreciated that an error is displayed if the type is array but the default value is of any other type.

This issue looks related to our Java services. Seeking confirmation from the Java team.

Confirmed. Moving to https://github.com/swagger-api/swagger-parser repository.
