Subject [GitHub] ignite pull request #1473: IGNITE-3196

    IGNITE-3196

    We shouldn't check sign at serialization, because the used approach:
    BigInteger intVal = val.unscaledValue();
    byte[] vals = intVal.toByteArray();
    #toByteArray() - already including at least one sign bit, which is (ceil((this.bitLength()
+ 1)/8)). (This representation is compatible with the (byte[]) constructor.)
    
    Therefore, at deserialization we just read  byte[] vals and scale, also we use default
constructor which will define a sign from byte[] vals.
