> The value Long.MAX_VALUE appears not to be decoded correctly all the time. (Perhaps the value's overflowing while being computed?) Here's a testcase:
> public class SimpleHelloWorld {
>     public static long long1 = -1;
>     public static long long2 = Long.MAX_VALUE;
>     public static void main(String args) {
>         System.out.println(long1 + long2);
>     }
> }
> I packed that with regular compression and then unpacked it. My BcBands.bcLongRef was [0, 1] instead of  [-1, 9223372036854775807].
> I've got another test case (proprietary code) which causes BcBands.bcLongRef to be [....., -1, -1 ....]. I'll send that to Sian by email. That's how I detected this issue - the two long refs were collapsed into one.
