> For large negative BIGINTs, zigzag encoding will yield large value (64bit
> value) with MSB set to 1. This value is interpreted as negative value in
> SerializationUtils.findClosestNumBits(long value) function. This resulted in
> wrong computation of total number of bits required which results in wrong
> encoding/decoding of values.
