ClassCastException (not always) for KeyValue async lookup

[RichardHightower]

We are seeing random classcastexception, from the looks of it the reactor callback is return invalid tool. Its not only invalid (or null) but a complete different type of object (here, Integer)

This is a possible issue with Boon or QBit. We will try to reproduce and at a minimum come up with better error reporting.

Exception:

I have not been able to reproduce this yet.
