Well, don't do
Node resNode = fileNode.addNode ("jcr:content", "nt:resource");
if the "jcr:content" subnode already exists. In this case do getNode().

The filename is stored in the nodename of the nt:file node. If it is
versioned, only its properties and the jcr:content subnode will be
stored with each version. The name doesn't change. To solve that, you
can set a property on the node (you'll need a custom mixin for that,
because nt:file doesn't allow unstructured date) and set it different
in each version. But you probably also want to make the node name more
generic, otherwise the node would always be named after file that
created the first version. But that depends on the semantics of your
app and content.
