I agree, I don't think we should couple the R code to the underlining data
source implementations, and was not suggesting that :)
I guess I'm saying there are still many (other) cases where the parameters
are unchecked and would be good if this check to convert JVM
IllegalArgumentException is sufficient or more checks should be added to the R
side.
