That is the way to do it yes.

implementation, yes. But as you can see
org.neo4j.kernel.impl.nioneo.xa.NeoStoreXaDataSource extends
org.neo4j.kernel.impl.transaction.xaframework.LogBackedXaDataSource which
has a correct implementation of that method. So your piece of code there
works they way you'd like.
