* Avoid parsing large big decimals Parsing large big decimals (thing tens of hundred digits) and operating on these numbers can be very CPU demanding. While play-json currently supports handling large numbers, it is not practical on real-world applications and can expose them to DoS of service attacks. This changes the way parsing happens to limit the size of such numbers based on MathContext.DECIMAL128. * Format details * Fix typo * Remove tests duplication * Add breadcrumbs detailing where precision is defined * Improve parsing readability * Improve test readability
Fixes #187 Parsing large big decimals (thing tens of hundred digits) and operating on these numbers can be very CPU demanding. While play-json currently supports handling large numbers, it is not practical on real-world applications and can expose them to DoS of service attacks. This changes the way parsing happens to limit the size of such numbers based on MathContext.DECIMAL128.
* Codec for BigInt * MiMa * More tests

Should we be concerned about Scala 2.11 users of DefaultReads/DefaultWrites? |

Actually, no one consumes DefaultReads/Writes extending objects to call methods off of it, at most they mix it in and then import its implicits off it. So no binary risk. |

These two commits are the cherry-pick of #200 and #191.
I want someone to review that the MiMa binary changes are ok for 2.6.x (because I suspect they're not).
