Babak Vahdat resolved CAMEL-7096.
---------------------------------
Resolution: Fixed
> The ObjectHelper#createIterator utility should properly adhere the
> java.util.Iterator contract
> ----------------------------------------------------------------------------------------------
>
> Key: CAMEL-7096
> URL: https://issues.apache.org/jira/browse/CAMEL-7096
> Project: Camel
> Issue Type: Bug
> Components: camel-core
> Affects Versions: 2.12.2
> Reporter: Babak Vahdat
> Assignee: Babak Vahdat
> Priority: Minor
> Fix For: 2.11.3, 2.12.3, 2.13.0
>
>
> According to the {{java.util.Iterator#next()}} contract the implementation
> should throw {{NoSuchElementException}} if the iteration has no more
> elements. However this is currently not the case by the different anonymous
> class implemetations of this interface through
> {{ObjectHelper#createIterator()}}.
> The side effect of this is that currently this could end up with
> {{IndexOutOfBoundsException}} and what not if one would iterate over the
> {{Node}}(s) of a DOM {{NodeList}}. Another example is that calling {{next()}}
> on the {{Iterator}} returned for an empty String *repeatedly* doesn't throw
> any {{NoSuchElementException}} *although* it's {{hasNext()}} method returns
> false!
> We should better provide guards for the condition when there's no more
> elements available in which case a {{NoSuchElementException}} should be
> thrown.
