Line 200 in 19234f1

future.complete(val);

We have gotten a couple exceptions running in production around the above line of code. The trace is:

java.util.concurrent.CompletionException: java.lang.NullPointerException

We are going to take a look at this on priority at some point coming up here, but wanted to drop it here in case the solution is obvious in some way. Any insight is certainly welcome as well.
