> Several bugs have been found caused by integer overflows in Tungsten. This JIRA is for taking a final pass before 2.0 release to reduce potential bugs and issues. We should do at least the following:
> * Raise exception early instead of NegativeArraySize
> * Document clearly the largest array size we support in DataFrames.
