cannot handle kotlin functions defined in the top level #9

if you change the kotlin sample app to use a top level function like this

fun main(body: String, @Header("name") name: String): String {
    return "Hello ${name}! I got payload `${body}` and I am on host: ${System.getenv("HOSTNAME")} and I am kotlin!"
}

then when you run it you get an error.

I wonder if this is a bug in camel trying to instantiate a class which does't have a contructor?

To reproduce this issue you can clone this repo:
https://github.com/fabric8-quickstarts/funktion-kotlin-example

then edit the [src/main/kotlin/io/fabric8/funktion/example/Main.kt])https://github.com/fabric8-quickstarts/funktion-kotlin-example/blob/master/src/main/kotlin/io/fabric8/funktion/example/Main.kt) file and comment out the class Main { wrapper; then modify the this funktion.yml line to use MainKt as the class name

Fixed by: https://issues.apache.org/jira/browse/CAMEL-10021

I changed the function to tell the user to specify a name if missing, and made the parameters optional

fun main(body: String?, @Header("name") name: String?): String {
    if (name != null)
        return "Hello ${name}! I got payload `${body}` and I am on host: ${System.getenv("HOSTNAME")} and I am kotlin!"
    else
        return "What is your name? Specify a name using ?name=foo as query parameter"
}

And the fix in Camel requires a new release such as the 2.17.2
