hi, I have a

final case class TreatmentAttribute(
    treatmentAttribute: com.grab.grabdefence.acorn.proto.JavaMap[_root_.scala.Predef.String, _root_.scala.Predef.String] = com.grab.grabdefence.acorn.proto.JavaMap.empty
    )

in a DataStream and want to convert it to a Table with

tableEnv.fromDataStream

com.grab.grabdefence.acorn.proto.JavaMap

extends

java.util.HashMap

and should therefor be bridged to a Flink SQL Map Type according to https://nightlies.apache.org/flink/flink-docs-release-1.15/docs/dev/table/types/#constructured-data-types. However that does not happen: it is a RAW type.

`treatmentAttributes` RAW('com.grab.grabdefence.acorn.proto.JavaMap', '...'),

why does it not get bridged to MAP as documented?
