> -------------------------------------------------------------------
>
> Key: GROOVY-7961
> URL: https://issues.apache.org/jira/browse/GROOVY-7961
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 2.4.7
> Reporter: John Wagenleitner
> Assignee: John Wagenleitner
> Priority: Minor
> Labels: breaking
> Fix For: 2.5.0-beta-1
>
>
> Calling {{next()}} on an {{ObjectRange}} iterator returns {{null}} when {{hasNext{}}} returns false. It should throw {{NoSuchElementException}} to adhere to the Iterator contract.
> {code}
> class ObjectRangeItrTest extends GroovyTestCase {
> void testItr() {
> def itr = ('a'..'b').iterator()
> assert itr.next() == 'a'
> assert itr.next() == 'b'
> assert !itr.hasNext()
> shouldFail(NoSuchElementException) {
> println itr.next()
> }
> }
> }
> {code}
