Steps to reproduce

@Bean(name = "org.openapitools.configuration.EnumConverterConfiguration.exampleUriEnumConverter")
    Converter<URI, ExampleUriEnum> exampleUriEnumConverter() {
        return new Converter<URI, ExampleUriEnum>() {
            @Override
            public ExampleUriEnum convert(URI source) {
