This change prevents latency explosions when working with high-magnitude
BigDecimal
values, while preserving the current behavior on the edge cases.It's fixes the original bug reported in FasterXML/jackson-databind#2141 but not the several related issues discussed therein. It builds atop my earlier PR #85
One challenge here is that the current two-step conversion process, using
BigDecimal.longValue()
andDecimalUtils. extractNanosecondDecimal()
separately, made it hard to control the edge cases because information is lost during the former. So I combined the two into a single helper method.(IMO these helpers shouldn't be public API, since they are bespoke semantics needed by this package, and unlikely to be usable by other contexts. Frankly I'd prefer to make the new helper method package-protected, if that's okay with the maintainers.)
