tryGetActor always fails

Actually I don't think the explanation is required here. But I found that error while was getting actor-ref by calling co.paralleluniverse.actors.ActorRegistry#tryGetActor. Stacktrace I've got is the following:

java.lang.IllegalArgumentException: Transaction may not be null for this operation.
    at co.paralleluniverse.galaxy.core.StoreImpl.verifyNonNull(StoreImpl.java:485)
