Suggest a fix

Either do throw a RuntimeException as configured or (even preferable in my use-case) give the option do NOT generate ApiException, ApiExceptionMapper, @RegisterProvider(ApiExceptionMapper.class) altogether.

If this is not desired for microprofile clients, this information should be added to the documentation.

Start with the Java generator's microprofile library using the provided sample YAML and generation command. Compare the generated api.ApiException with the expected root-package ApiException and verify whether useRuntimeException=true affects the generated exception behavior and related artifacts. No repository file or test is named, so done means reproducing the issue and adding coverage for the corrected output.
