> GenerateUnsafeProjection.writeStructToBuffer() does not honor the assumption that one
should first make sure the value is not null before calling the getter.
> An example of generated code:
> {noformat}
> /* 059 */         final UTF8String fieldName = value.getUTF8String(0);
> /* 060 */         if (value.isNullAt(0)) {
> /* 061 */           rowWriter1.setNullAt(0);
> /* 062 */         } else {
> /* 063 */           rowWriter1.write(0, fieldName);
> /* 064 */         }
> {noformat}
