----------------------------------

             Summary: Use of a negative range with Long values results in reversed sequence
                 Key: GROOVY-9969
                 URL: https://issues.apache.org/jira/browse/GROOVY-9969
             Project: Groovy
          Issue Type: Bug
          Components: groovy-runtime
    Affects Versions: 2.5.14, 2.5.12
            Reporter: Sean Fitts


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.
