Would be nice if "oneof" types were implemented a common sealed interface for pattern matching purposes

Is your feature request related to a problem? Please describe.

if there is a "oneof" referencing 2 types, it would be nice if both could extend a common sealed interface and that the oneof types both are records.

Hello @gurgl , thank you for the suggestion!

I will investigate it and assess the scope - regardless, it will likely be the highest prio item in the backlog.

On further inspection of this, it would require JDK 17+ to be used - which is not enforced by openapi-generator-maven-plugin. Hence, while this would be neat for a JDK 17+ solution, the desire is to remain as close to openapi-generator-maven-plugin as possible - while improvements to formatting, documentation and refactoring can be done as long as it keeps the original behaviour and functionality.

Although, using records should already imply JDK-17+... 🤔

Seems like openapi-generator-maven-plugin added support for something similar: OpenAPITools/openapi-generator#20503

Will investigate adding support for it
