Why not?

  List<VMSnapshot> snapshots = vm.getSnapshots().list();
  for (VMSnapshot snapshot : snapshots) {
    System.out.println(snapshot.getId());
  }

What you can't do, if understand correctly, is assign your own unique
symbolic name to a snapshot, like you do with the VM "name" attribute,
for example. That is a limitation of the engine, snapshots don't have a
"name" attribute.

Currently your only chance is to use the "description" attribute, but as
you said there is no guarantee that it will be unique.

Note that this happens with the Java SDK, with the Python SDK or with
any other client.
