Vova Shelgunov reopened CAMEL-10399:
------------------------------------

After discussing this issue in mailing list with Tomohisa, it seems that there 
is a bug in DefaultHttpBinding.populateRequestParameters, when file parameter 
is processed twice (when it already processed in 
DefaultHttpBinding.populateAttachments).
