The move you requested asked to move the /AB:Entities[2] node into a
new root-level node with the name "AB:Entities". Since there already
was another node with the same name, the node ended up as a same-name
sibling, i.e. /AB:Entities[2]. Thus, nothing seemed to change.

The move method can not be used to merge two nodes into one, you need
to explicitly move each child node of /AB:Entities[2] to /AB:Entities.
Use something like this:

    Node root = session.getRootNode();
    Node node1 = root.getNode("AB:Entities");
    Node node2 = root.getNode("AB:Entities[2]");
    NodeIterator iterator = node2.getNodes();
    while (iterator.hasNext()) {
        Node child = iterator.nextNode();
        session.move(child.getPath(), node1.getPath() + "/" + child.getName());

This will move all the AB:Entity nodes under /AB:Entities[2] to the
end of the child list of /AB:Entities and remove the remaining empty
/AB:Entities[2] node.
