How to use Tinkerpop with actors

I would like to know if I can use tinkerpop within Akka Futures, so far when I commit my changes to the graph they don't get persisted. I understand tinkerpop is a thread-local library which mean I'd need to set my thread again within the future ODatabaseRecordThreadLocal.INSTANCE.set(thread)

I tried the following method without success :

def test[T](graphChanges: => T): T = {
    val thread = ODatabaseRecordThreadLocal.INSTANCE.get
    try graphChanges finally {
      ODatabaseRecordThreadLocal.INSTANCE.set(thread)
      GraphPool.get("partitioned").commit
    }
}

// collect tinkerpop frames
test {
  future {
  // add changes to my tinkerpop frames
  }
}

I would like to have on Tinkerpop thread per play.mvc.Http.Context

Here is a sample project with what I want to achieve : https://github.com/D-Roch/tinkerpop-play
