Romain Manni-Bucau resolved JOHNZON-110.
----------------------------------------
Resolution: Fixed
Fix Version/s: 1.1.0
> Support for large integrals
> ---------------------------
>
> Key: JOHNZON-110
> URL: https://issues.apache.org/jira/browse/JOHNZON-110
> Project: Johnzon
> Issue Type: Improvement
> Affects Versions: 0.9.5
> Reporter: Michele Vivoda
> Fix For: 1.1.0
>
>
> While testing javax.json implementations I discovered Johnzon does not
> support very big integral numbers , they loose the value when converted to
> Long and might also become negative. Big decimals works fine.
> Other implementations tested, the glassfish one and cookjson both support big
> integrals as java.math.BigInteger
> I would suggest to test the length of an integral lexical without sign
> (being an integral has no decimals, no exponential part) , if is more than 18
> digits, use java.math.BigInteger
> See also the implementation of Glassfish
