I agree -- it would indeed be helpful if someone researched this
independently.

Last night while working with this example, it correctly decrypted using
effective key bits of 128:

SMIMECryptUtil  - version is 58

SMIMECryptUtil  - RC2 version 58 maps to effective key length 128

SMIMECryptUtil  - iv

SMIMECryptUtil  - Cipher 1.2.840.113549.3.2 maps to encryption algorithm
RC2/CBC/PKCS5Padding

EnvelopedData  - Back from handleEncryptedContentInfo, looks like
everything decrypted

EnvelopedData  - Data was decrypted

TestEnvelopedData  - Content bytes:
0000 54 68 69 73 20 69 73 20 73 6F 6D 65 20 73 61 6D  This is some sam
0010 70 6C 65 20 63 6F 6E 74 65 6E 74 2E              ple content.
