Beta docker image java lib branch/connection

Howdy,
Which version of java-lib jar or branch of repository should we be using for the betanet local docker image?
Also for connection should we be using LOCALHOST_SINGLENODE?

RadixApplicationAPI api = RadixApplicationAPI.create(Bootstrap.LOCALHOST_SINGLENODE, radixIdentity);

I’ve been getting serialization errors on missing classes.

Thanks,
–jim
