David,
I have updated to latest 1.50 version. It does not change our situation. Files are \
still there with unencrypted content. Could it be issue in some of JDK's smime/jce \
related classes ?

No SMIMESignedParser wouldn't be used for that, you'd need to be calling it \
explicitly.
I just noticed you said you were using 1.47. Would you try using the 1.50 release and \
see if you still have the problem? It's possible 1.47 made wider use of backing store \
(I thought we'd managed to sort this out quite a while ago, but then I guess 1.47 was \
quite a while ago...)
If you can send me the smallest functioning program you can write that causes it I \
might be able to suggest something for 1.47. I would strongly recommend moving to \
1.50 though.
Regards,
David

Okay, I'm pretty sure these are connected with the use of SMIMESignedParser. You'll \
need to use the constructor that allows you to provide your own backing store.

What are the files called? The SMIMESignedParser does need a backing file, but there \
is a constructor that allows you to pass in a defined one rather than letting the API \
do it for you. I don't think anything else uses them though (mind you it's been a \
while since I looked at it...) Can you tell me more about what your are seeing?

I'm using 1.47 version of Bouncy Castle library.
Here is my code snippet
SMIMEEnvelopedGenerator gen = new SMIMEEnvelopedGenerator();
gen.addRecipientInfoGenerator(new \
JceKeyTransRecipientInfoGenerator(ourCertificate).setProvider("BC")); if \
(otherRecipientsCertificate != null) {
for(int i=0; i < otherRecipientsCertificate.size(); \
i++) gen.addRecipientInfoGenerator(new \
JceKeyTransRecipientInfoGenerator((X509Certificate)otherRecipientsCertificate.get(i)).setProvider("BC"));
}
MimeBodyPart msg = new MimeBodyPart();
msg.setDataHandler(new DataHandler(new \
BinaryBatchDataSource(in)));
msg.setHeader("Content-Type", "application/octet-stream");
msg.setHeader("Content-Transfer-Encoding", "binary");
MimeBodyPart mp = gen.generate(msg, new \
JceCMSContentEncryptorBuilder(CMSAlgorithm.AES256_CBC, \
256).setProvider("BC").build());
Properties props = System.getProperties();
Session session = Session.getDefaultInstance(props, null);
MimeMessage body = new MimeMessage(session);
body.setContent(mp.getContent(), mp.getContentType());
body.saveChanges();
body.writeTo(os);
