> Use of long values when describing an array range results in a reserved result when it should not.
> For example, the following is true in 2.5.11 and false starting in 2.5.12:
> {code:java}
> [1L, 2L, 3L, 4L, 5L, 6L][(2L .. -2L)] == [3L, 4L, 5L]
> {code}
> The following however is true in all versions of 2.5:
> {code:java}
> [1L, 2L, 3L, 4L, 5L, 6L][(2 .. -2)] == [3L, 4L, 5L]
> {code}
> I believe this bug was introduced in the fix for https://issues.apache.org/jira/browse/GROOVY-8966.  The NumberRange produced reverses the from and to resulting in the reversed sequence.
