Is there a more kotlin-y way of doing this. In this instance JsonDataClassHolder is an interface, which many different types can implement.

fun <T : JsonDataClassHolder> findProfile(
        content: String,
        clazz: Class<T>
    ): T {
  return mapper.readValue(contentRaw, clazz)
}

I also tried

fun <T : JsonDataClassHolder> findProfile(
        content: String
    ): T {
  val type = object : TypeReference<T>() {}
  return mapper.readValue(contentRaw, type)
}

but got the following error:

Cannot construct instance of `JsonDataClassHolder` (no Creators, like default construct, exist): abstract types either need to be mapped to concrete types, have custom deserializer, or contain additional type information

An example of how I'd like to call this function might be:

private data class CoolJson(
            val status: String
        ) : JsonDataClassHolder

findProfile<CoolJson>("""{'status': 'cool'""")
}

I liked how I only needed to pass the type as a type parameter versus in my working example as a function variable.

I guess the kotlin way would be to make the reified inline, but i would like to avoid that as well in this case.
