@smarek when i up more than ten files ,i have get an OOM for this ,and wo cannt do this oom

@smarek see #545

Oh, so closing, to not duplicate the issue

@smarek when I upload more than one file , web server'll throw Excetion.
the message like: processing of multipart/form-data request failed, stream ended unexpectedly. so I write a jsp page then upload file use a form which's ENCTYPE="multipart/form-data" then web server don't throw exception;
so i think it's there some problem about the httpclient's request property?
a original way to upload file like this:
conn.setRequestProperty("Content-Type", multipart_form_data + "; boundary=" + boundary);
I hope you can give me an answer
