@shivaram added unit tests.
On Java Array limitation, we deserialize all of the arguments as one
Array[Object]. So if even one of the arguments is larger than `INT_MAX` we will
fail on the R side. But with this patch we can still handle those. There is
still a problem when number of arguments is larger than INT_MAX. Am I missing
another case?
