[Springframework-developer] Re: [Springframework-user] Re: Send email with attachment

After doing some debugging, I think I found a (bug?) in
MimeMessageHelper.createDatasource(). The method creates an anonymous
instance of javax activation DataSource with getInputStream() impl
which calls inputStreamSource.getInputStream(). It all works fine for
all the InputStreamSources except for InputStreamResource which allows
to read wrapped InputStream only once, therefore throwing
IllegalStateException whenever java mail classes e.g. Transport tries to
call DataSource.getInputStream() multiple times.
Juergen, would it be reasonable to pass a raw InputStream into
MimeMessageHelper.createDatasource() or as an alternative "disallow"
usage of InputStreamResource in MimeMessageHelper? I'd rather do the
former.
Regards,
Dmitriy.
