> private void writeDataFlow(final File file, final ClusterDataFlow
> clusterDataFlow) throws IOException, JAXBException {
> // get the data flow

> // if no dataflow, then write a new dataflow
> if (dataFlow == null) {
> //dataFlow created but not used
> dataFlow = new StandardDataFlow(new byte[0], new byte[0], new
> byte[0]);
> }
> // setup the cluster metadata
> final ClusterMetadata clusterMetadata = new ClusterMetadata();
> clusterMetadata.setPrimaryNodeId(clusterDataFlow.getPrimaryNodeId());
> // write to disk
> //write the unmodified clusterDataFlow
> //if the clusterDataFlows dataFlow element is null a getEmptyFlowBytes() is
> written
> writeDataFlow(file, clusterDataFlow, clusterMetadata);

> {code}
> Not clear if the null check is ever true but if it is the new DataFlow is not
