If I'm reading this (and the `insufficientCapacities()`) correctly, then it appears that we are testing the "edge" capacities. I think including at least one more arbitrary capacity value which isn't an "edge" might be good too. Something like:

final long randomCapacity = new Random(RESPONSE_BODY.length + 1, Long.MAX_VALUE);

Similar idea for `insufficientCapacities()`.
