An update on the ongoing effort to use jarsigner on the certificate from Barcelona, clipped from SAK-410:
Tried using the certificate by just creating a keystore on import of that cert... used 'audioApplet' as the alias... but I ran into the following error:
jarsigner: Certificate chain not found for: audioApplet. audioApplet must reference a valid KeyStore key entry containing a private key and corresponding public key certificate chain.
Tried the keytool import with both trustcacerts and without. Doesn't seem to make a difference.
