Eric Chatellier commented on CXF-8669:
--------------------------------------
Hi,
I investigated a lot this bug.
In version {+}3.4.3{+}, for *Long* parameter, *_Attachment#getContentType()_*
returns _MediaType.TEXT_PLAIN_TYPE_ because
{*}AttachmentDataSource.{*}*getContentType()* also return "null".
So "{_}text/plain"{_} parameters are handled by *PrimitiveTextProvider* and
then converted to {*}long{*}.
In version {+}3.5.5{+}, there is a change in
{*}AttachmentDataSource.{*}*getContentType()* returning a default
_"__application/octet-stream"_ content type (maybe due too [this
commit|[https://github.com/apache/cxf/commit/d27ad0157e49fdd601f702823155ff813880de5b].]
There is no MessageBodyReader implementation to hander
{_}application/octet-stream{_}, so parameter is not converted and this result
to "{_}null{_}" value.
Hope this helps

> Hello Team,
> I have following API declaration
> {code:java}
> @POST
> @Path("/{configurationName}.diff")
> @Consumes(MediaType.MULTIPART_FORM_DATA)
> @Produces({MediaType.APPLICATION_JSON})
> ConfigurationDiffDTO diff(@PathParam("configurationName") String
> configurationName,
> @Multipart(value = "fromRev", required = false) Long fromRev,
> @Multipart(value = "toRev", required = false) Long toRev, @Multipart(value =
> "file", required = false) Attachment file);
> {code}
> Above declaration works fine till 3.4.5 , after I upgraded to 3.5.0 (even
> 3.4.6) , multipart form values (fromRev and toRev) they are coming as null.
> Is it a regression?
