Multiple file upload using Quarkus and RestEasy

I am trying to set up an endpoint that allows multiple file upload, along other form data. Consider this like a create product page, where you would have a couple of product images but also other information. Ideally I want to map the request to a POJO

@POST
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces(MediaType.APPLICATION_JSON)
@Path("/product/create")
public Response createProduct(@MultipartForm CreateProductRequest req)  {

And the POJO:

@Data
public class CreateProductRequest {

@FormParam("name")
private String name;

@FormParam("description")
private String description;

@FormParam("tags")
private List<String> tags; 

@FormParam("img")
@PartType(MediaType.APPLICATION_OCTET_STREAM)
private List<InputStream> img; //Ideally I could use an object such as MultipartFile 
                               //that would give me access to the filename and MIME type

}

But this doesn't work, I get:

java.lang.RuntimeException: RESTEASY007545: Unable to find a MessageBodyReader for media type:
image/jpeg;charset=UTF-8 and class type java.util.List

If I remove the List, it works fine.

And it seems its the same issue with List<String> tags

Which throws :

java.lang.RuntimeException: RESTEASY007545: Unable to find a MessageBodyReader for media 
type: text/plain;charset=UTF-8 and class type java.util.List

I've seen workarounds using MultipartFormDataInput but i would really like to avoid that since the request obj is pretty large, and mapping it by hand would be very tedious and error prone.

I am running Java 11, Quarkus 1.11.1.Final

Many thanks!
