OpenJDK BigDecimal::doubleValue() goes via a string in certain situations https://github.com/openjdk/jdk/blob/master/src/java.base/sha...

I just ran into a similar booby trap the other day: whereas BigDecimal::BigDecimal(double) does the full decimal expansion, BigDecimal::valueOf(double) goes through Double::toString(double), which is generally a lot fewer digits.
