> The CI flagged failing tests are not stemming from any code that I have
touched,
> How to resolve?
Click on the link of the failed Travis CI builds. Then choose one of the JDK
versions (e.g. 8). There you should find the logs of the job that failed. [For
instance](https://travis-ci.com/github/apache/commons-collections/jobs/508633788):
>[ERROR]
src/test/java/org/apache/commons/collections4/iterators/PairedIteratorTest.java:[149,3]
(indentation) Indentation: 'method def rcurly' has incorrect indentation level
2, expected level should be 4.

> ZippingIterator provides a way to simulatenously iterate over multiple
> iterators of the *same-type.*
> The proposed pair iterator allows simultaneously iterating over two iterators
> of different type, like the example below:
> {code:java}
> Iterator<L> leftIterator = ...;
> Iterator<R> rightIterator = ...;
> PairIterator<L,R> pairIterator = PairIterator.of(leftIterator, rightIterator);
> while (pairIterator.hasNext()) {
> ImmutablePair<L,R> item = pairIterator.next();
> ...
> }{code}
>
> Another convenience could be to use an Iterable for easy for-each constructs.
> {code:java}
> List<Integer> studentIds = ...
> List<String> studentNames = ...
> for (PairedItem<Integer, String> items :
> IterableUtils.pairedIterable(studentIds, studentNames) {
> Integer studentId = item.getLeft();
> String studentName = item.getRight();
> ...
> }
> {code}
