	- @Inject field org.acme.GreetingResource$ErrorMapper#request

get sample kotlin app - https://code.quarkus.io/?e=kotlin&extension-search=origin:platform quarkus-kotlin
extend GreetingResource.kt
run mvn clean package -DskipTests and check the log

GreetingResource.kt:

package org.acme

import io.quarkus.logging.Log
import io.vertx.core.http.HttpServerRequest
import javax.inject.Inject
import javax.ws.rs.GET
import javax.ws.rs.Path
import javax.ws.rs.Produces
import javax.ws.rs.WebApplicationException
import javax.ws.rs.core.MediaType
import javax.ws.rs.core.Response
import javax.ws.rs.ext.ExceptionMapper
import javax.ws.rs.ext.Provider

@Path("/hello")
class GreetingResource {

    @GET
    @Produces(MediaType.TEXT_PLAIN)
    fun hello() = "Hello from RESTEasy Reactive"

    @GET
    @Path("/fail")
    fun getFail() {
        throw WebApplicationException("Custom fail", 404)
    }

    @Provider
    public class ErrorMapper : ExceptionMapper<Exception> {
        @Inject
        public var request: HttpServerRequest? = null

        override fun toResponse(exception: Exception): Response {
            Log.info("Exception for client " + request!!.remoteAddress());

            var code = 500
            if (exception is WebApplicationException) {
                code = exception.response.status
            }
            return Response.status(code).build()
        }
    }
}
