SLF4J and http4k-client-websocket

Steps to reproduce:

1. add dependencies:

implementation(group: "org.http4k", name: "http4k-core", version: "3.226.0")
implementation(group: "org.http4k", name: "http4k-server-jetty", version: "3.226.0")
implementation(group: "org.http4k", name: "http4k-client-websocket", version: "3.226.0")

1. write simple main

fun main() {
    websockets(
        "/ws" bind { ws: Websocket -> }
    ).asServer(Jetty(8080)).start()
}

Output from console:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

If you remove http4k-client-websocket dep, then logging works.

Yep - it’s quite an annoying warning TBH, but we do want to avoid having a dependency on any implementation, so closing this unless we think there’s anything else to add. 😃

Sorry about that. So in the end I’d have to add this dep to my project, even if I don’t use it directly?
