Hmm, I don't have a java client that does all this. All of my stuff is in
erlang using the thrift client.
I can certainly raise a ticket and describe the problem though.
If the CLI supported querying by index I'd see if I could knock up an script
that did it but I don't think it does.
If you wanted a Java test case it would take me quite a while as I am
completely unfamiliar with the Java client api.
I'll raise a descriptive ticket for now and see where we go from there.
