Steps To Reproduce:

1. Create a POJO Based Multipart form containing one or more byte arrays/InputStreams( for file upload)
2. Create a Service accepting that form work on post method
3. Deploy it on Jboss-5.0
4. Make a multipart form and open it on firefox
5. Select file and submit the form

Observed:

There is an exception on server stating "Unable to find @FormParam in multipart: fileData"
This only happens if there is a file in the form, otherwise it works fine.

Expected:

Multipart forms should be able to accept files because in case file upload is not support there is no point of multipart form

Problem/Work around:
I think problem exist with the RE for content disposition header (in org.jboss.resteasy.plugins.providers.multipart.MultipartFormDataInputImpl) that group everything after name="" causing partname to be filename rather parameter name in case of file upload.

Current RE = "form-data;.name=\"?([^\"\\s;])\"?.*"

Can be fixed by changing RE to "form-data;.name=\"(.?)\"."
