Benson Margulies commented on CXF-3987:
---------------------------------------
In 2.5.0, the wire data looks rather similar, so the mystery is, why is the
ContentDisposition reference null?

> Key: CXF-3987
> URL: https://issues.apache.org/jira/browse/CXF-3987
> Project: CXF
> Issue Type: Bug
> Components: JAX-RS
> Affects Versions: 2.5.1
> Reporter: Benson Margulies
>
> One of my multipart tests is now failing with a 400. The 400 is thrown from
> FormUtils in the runtime. It runs just fine in 2.5.0.
> My function looks like:
> {code}
> @Produces("text/html")
> @Consumes("multipart/form-data")
> @Path("/processFormTextToJson")
> @Descriptions({
> @Description(value = "Accepts text from an HTML form, returns
> analysis results in JSON.", target = DocTarget.METHOD),
> @Description(value = "Json containing all of the analysis results",
> target = DocTarget.RETURN)
> })
> public Response processFormTextToJson(@Description(value = "Json
> specification of the processing options.", target = DocTarget.PARAM)
> @Multipart(value = "options")
> String optionsString,
> @Description(value = "Input text",
> target = DocTarget.PARAM)
> @Multipart(value = "data")
> InputStream data) {
> {code}
> and the code leading to the exception in CXF is:
> {code}
> public static void populateMapFromMultipart(MultivaluedMap<String, String>
> params,
> Annotation[] anns,
> MultipartBody body,
> boolean decode) {
>
> List<Attachment> atts = body.getAllAttachments();
> for (Attachment a : atts) {
> ContentDisposition cd = a.getContentDisposition();
> if (cd == null ||
> !MULTIPART_FORM_DATA_TYPE.equalsIgnoreCase(cd.getType())
> || cd.getParameter("name") == null) {
> Multipart id = AnnotationUtils.getAnnotation(anns,
> Multipart.class);
>
> if (id == null || id.required()) {
> throw new WebApplicationException(400);
> } else {
> return;
> }
> }
> {code}
> The annotations present are:
> {noformat}
> [@org.apache.cxf.jaxrs.model.wadl.Description(title=, target=param,
> value=Json specification of the processing options., lang=, docuri=),
> @org.apache.cxf.jaxrs.ext.multipart.Multipart(value=options, required=true,
> type=*/*)]
> {noformat}
> Note that the required flag is on. cd is null. In other words, even if the
> names match, if there is no content disposition, we get a 400. Is that really
> right? Why require a cd? What's wrong with the plain old name field of the
> part?
