Support running the gateway with other reactive containers besides netty

I am trying to use tomcat instead netty. To achive this i have excluded netty from dependencies and included tomcat, so my build.gradle dependecies:

dependencies {
    compile (group: 'org.springframework.cloud', name: 'spring-cloud-starter-gateway', version: '2.0.0.M4') {
        exclude group: 'org.springframework.boot', module: 'spring-boot-starter-netty'
    }
    compile group: 'org.springframework.boot', name: 'spring-boot-starter-tomcat', version: '2.0.0.M7'
    compile group: 'org.springframework.boot', name: 'spring-boot-starter-webflux'
}

Hower it is not enough, i get ClassCastException:

java.lang.ClassCastException: org.springframework.core.io.buffer.DefaultDataBufferFactory cannot be cast to org.springframework.core.io.buffer.NettyDataBufferFactory
	at org.springframework.cloud.gateway.filter.NettyWriteResponseFilter.lambda$filter$0(NettyWriteResponseFilter.java:61) ~[spring-cloud-gateway-core-2.0.0.M4.jar:2.0.0.M4]
	at reactor.core.publisher.MonoDefer.subscribe(MonoDefer.java:44) ~[reactor-core-3.1.1.RELEASE.jar:3.1.1.RELEASE]
	at reactor.core.publisher.Mono.subscribe(Mono.java:2913) ~[reactor-core-3.1.1.RELEASE.jar:3.1.1.RELEASE]
	at reactor.core.publisher.MonoIgnoreThen$ThenIgnoreMain.drain(MonoIgnoreThen.java:167) ~[reactor-core-3.1.1.RELEASE.jar:3.1.1.RELEASE]

Is it possible to use tomcat with gateway instead netty?
Thanks!

Start with NettyWriteResponseFilter.java and the build.gradle dependency setup shown in the report, then reproduce the ClassCastException using the listed Tomcat and WebFlux dependencies. Done means the gateway can run with Tomcat instead of Netty without the Netty-specific buffer cast failure.
