The method is effectively (but without expensive string conversions): new BigInteger(Long.toUnsignedString(v)); I do not have a use case for it other than testing unsigned integer math implementations. It could be used to create a valid number when using a long counter that has overflowed to negative. A possible home is in [Lang]: org.apache.commons.lang3.math.NumberUtils That class has some conversion methods to BigDecimal for floating-point numbers with rounding to a number of significant digits. So creating BigInteger beyond the support of the JDK methods is in scope. Without a use case it would just be code bloat.
