Review comment:
I mean instead `if (condition) throw new IllegalStateException(msg)` you can
just replace it with `checkState(condition, msg)?
But ok, `checkPutStateConditions` could be on the hot path, so it might be a
good idea to hide creating the `msg` inside the `if` branch, so the message is
not created every time.
