When you use getObject() you are expected to pass in a CMIS Object ID. Those are defined by the spec as opaque which means you are not to infer any meaning from them. By constructing the ID yourself, you are violating that and are setting yourself up for heartache down the road when Alfresco changes how it creates object ID's. We're free to do that without warning because, as I said, those are opaque strings.

So, to be clear: Do not construct your own object ID's and expect them to work going forward.

The API has plenty of methods related to retrieving the version tree and fetching specific versions. Look at the JavaDoc and let me know if you can't find what you need.
