> There are couple of bugs in the MultiPartFormHandler because of which it is
> loosing a byte during the upload process. The two bugs are:
> 1. The MultiPartFormHandler$MultipartFormItem$MultipartInputStream wraps the
> ServletInputStream and maintains its own buffer. For every read request
> fills up the buffer by doing multiple reads on the ServletInputStream and
> serves the data from its buffer during a read operation. There was some bug
> in the complex buffering logic where it was dropping a byte. The fix is to
> not to fill up the buffer from the ServletInputStream and instead go to the
> ServletInputStream.readLine whenever necessary for every read operation.
> Similar fix needs to be applied in the
> MultiPartFormHandler$MultipartFormItem.writeFile logic since it is doing the
> same logic
> 2. There was a bug in the _readLine logic of MultiPartFormHandler. It was
> dropping a byte under certain rare circumstances where the internal buffer
> was getting full and when the last character read was a CR.
