I'm still interested though... Are you using the new "getChildren" api 
that was added to the client in 3.3.0? (it provides a Stat object on 
return, the old getChildren did not). While we don't officially support 
3.3.0 client with 3.2.2 server (we do support the other way around), 
there shouldn't be they type of problem with this configuration as you 
describe. I'd still be interested for you to create that jira.

Regards,

Patrick
