Now to throw my own spanner into the works. I've got the latest HEAD
FedOne up and running and am utilising a cert from startcom with a
private key I generated myself. While I can recieve from wavesandbox
(yay for character by character and sub blips!) I can't actually send.
When I do try and submit an operation I get something like the
following:

getDeltaSignerInfo
SEVERE: incoming getDeltaSignerInfo: cannot find signer info for signed
delta (breach of contract!)

Here's the relevant part of the run-config:

PRIVATE_KEY_FILENAME=wave_cert.key
CERTIFICATE_FILENAME_LIST=wave_cert.cert,sub.class1.xmpp.ca.crt

As you can see I've chained the certs, however that isn't preventing
errors like the following:

Caused by: java.security.cert.CertPathValidatorException: subject/issuer
name chaining check failed

If anyone has any clues that would be most appreciated.
