Scalac warns about "match may not be exhaustive" for specific record with map type

[mkuthan]

If project defines restrictive Scala flags like -Xfatal-warnings the compilation of generated specific records fail if there is a map in the schema.

SampleAvroClass.scala:69:9: match may not be exhaustive.
It would fail on the following input: (x: Any forSome x not in java.util.Map[?,?])

Corresponding fragment of the generated specific record:

case 4 => this.mapField = {
  value match {
    case (map: java.util.Map[_,_]) => {
      scala.jdk.CollectionConverters.MapHasAsScala(map).asScala.toMap map { kvp =>
        val key = kvp._1.toString
        val value = kvp._2
        (key, value.toString)
      }
    }
  }
}.asInstanceOf[Map[String, String]]

I would opt for adding unchecked annotation in the generated code.
