ParsingException reading P7M file

Hi all,

I have a problem reading a P7M file with sun.security.pkcs.PKCS7 class.

The exception is thrown by the last code line:

[...]

FileInputStream fis = new FileInputStream("c:\\test\\file.pdf.p7m");

PKCS7 pk = new PKCS7(fis); <----- ERROR !!!

[...]

The Exception is:

sun.security.pkcs.ParsingException: IOException: toDerInputStream rejects
tag type -96

I have created the P7M file with an "official" application that reads
Certificate from a Smart Card, and I have checked it with another "official"
application that correctly reads the file.

Thank you, Vittorio Avallone

Maybe it's incorrectly encoded and the 'official' application
is more forgiving than Sun's internal classes? What does a utility
like Peter Gutmann's dumpasn1 [1] or bouncycastle's ASN1
implementation say?
