ArrayIndexOutOfBoundsException on getFieldByNumber about scalapb HOT 5 CLOSED

Unrecognized enums override scalaValueDescriptor to give a descriptor that represents the unknown value, see here

from scalapb.

Assuming the message also contains Status status = 7 above.

Confirming the behavior you are seeing. There isn't a straightforward fix because as far as I can tell there's no public method in the Java protobuf API to instantiate an EnumValueDescriptor that represents an unknown enum. Is it possible for your code to use getField instead of getFieldByNumber at least for enums?

Yes, sorry for that.

No, it's not easily possible to substitute and I don't think it would help either. We would race into the same issue, just on a different place, specifically here.

Since the original issue (on getFieldByNumber) doesn't have a reasonable fix there isn't much that can be done to address it (I consider deprecating the method in a future release as it predates the PValue API used by getField). I wanted to check in if getField provides a reasonable alternative or you have any other suggestion.

Unfortunately migrating to getField would require quite a few changes on our side, so it's a no go for us at the moment.
