CDF JSON generation leads to java memory error/tabulation failure #550

Rosemary was working with a Minneapolis ES&S CVR and tried to generate the CDF JSON, but her tabulation failed when the Tabulator attempted to generate the file. Here's the errors she got in the log:

Addressing #301 might mitigate this; completing #247 would probably resolve it entirely. We've been aware of this limitation (in general) but haven't bothered to address it. Do you think it's something we should prioritize?

Doesn't seem like a priority. Not until the CDF gets more broad adoption, which will be a few years.
