> Hi, I've upgraded my code from Http Commons to HttpClient 4.2.1. My code worked well tell this event. I got an arrayOutOfBound exception (multipart getCount() = 1) on the line 11 of the folowing code. The first InputStream inP1 was troncated (not complete).

> import javax.mail.BodyPart;

> 	}
> 	public OutputStream getOutputStream() throws IOException {
> 		return null;
> 	}
> }
> I found a solution to patch this bug, by changing line 7, by this :
> 7   DataSource ds = new DataSourceForHttpResponseMultipart(new ByteArrayInputStream(IOUtils.toByteArray(responseAsStream)));
> I would like to find out why this happens and if it exists another solution by avoiding javax.mail and javax.activation...
> Thanks.
