Suggest a fix

Based on https://github.com/OpenAPITools/openapi-generator/issues/2701 it seems the latest swagger parser should have fixed the issue. However, even with 5.0.0 SNAPSHOT version of openapi-generator which is using a newer swagger parser version (2.0.20) I am still seeing this issue. Any help is appreciated.
