Michael McCandless created TIKA-986:
---------------------------------------
Summary: NullPointerException trying to parse detached .pk7s
signature
Key: TIKA-986
URL: https://issues.apache.org/jira/browse/TIKA-986
Project: Tika
Issue Type: Bug
Reporter: Michael McCandless
Assignee: Michael McCandless
Fix For: 1.3
Our Pkcs7Parser tries to pull the signed content out and then parses
that, but if the signature is detached then there is no content (we
get null return from CMSSignedDataParser.getSignedContent) and we hit
NPE:

I think fix is trivial: if we get null return then throw a
TikaException saying there's nothing to extract.
