Could not resolv e placeholder 'idp.encryption.cert'

[BPottier at andovercos.com]

I keep getting this stack trace and I dopn’t know why. I haven’t done anything out of the ordinary and credentials.xml and idp.properties looks fine. Does anyone have a clue? I’m running the newest version of shibboleth under tomcat8 on ubuntu.
