It's a little bit of a guess, but the class name
$line103090609224.$read$FeatureModder looks like something generated by the

this later and loaded it you may not find it matches up. Can you declare
this in a package?

DefaultParamsReadable[FeatureModder] {
val uid: String = "FeatureModder"+randomUUID
final val inputCol: Param[String] = new
