HCOLL-192 I've reviewed the code around this, it looks like this size constraint was a hang up from when we only allowed replicated entries to be no larger than max unsigned short, the underlying code was changed recently when we introduced the stateless client to allow much larger payloads. As such I've have increased this constrain to Integer.MAX_VALUE
