-----------------------------
> Range members should be final
> -----------------------------
>
> Key: GROOVY-7574
> URL: https://issues.apache.org/jira/browse/GROOVY-7574
> Project: Groovy
> Issue Type: Improvement
> Components: groovy-runtime
> Reporter: Thibault Kruse
> Assignee: Paul King
> Priority: Minor
> Fix For: 2.5.0-alpha-1
>
>
> The implementations of Range groovy.lang.ObjectRange and groovy.lang.IntRange
> have private members that are not final. This means that they can be modified
> via Groovy. However, if modified both implementations can easily be brought
> into inconsistent state, as they were implemented in Java under the
> assumption that private members cannot change.
> I suggest making the members final, such that instances of the range classes
> become immutable.
> EDIT: See https://github.com/apache/incubator-groovy/pull/109
