Also... >What you showed that the stream receiver called invoke() and did not get an answer, not a deadlock.
It's not that I'm getting back a null, it's that all the threads are blocked waiting on the invoke() call, and no progress is being made. That sounds a lot like a deadlock. I guess you could say the problem is that it's just never returning, but that seems like a distinction without a difference. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
