UndertowWebServerFactoryCustomizer does not support Options but only UndertowOptions

[tjuchniewicz]

UndertowWebServerFactoryCustomizer can map properties from:

• server.undertow.options.server.*
• server.undertow.options.socket.*
  into:
• builder.setSocketOption(...)
• builder.setSocketOption(...)

but it does not support org.xnio.Options but only UndertowOptions, see: https://github.com/spring-projects/spring-boot/blob/master/spring-boot-project/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/web/embedded/UndertowWebServerFactoryCustomizer.java#L141

To use builder.setSocketOption(...) we need properties from org.xnio.Options.

Thanks for the report. This looks like a bug to me. As far as I can tell, none of the options on UndertowOptions is intended for use as a socket option. This means that the server.undertow.options.socket.* properties are of no use as currently implemented.
