Please post code that compiles (the first example doesn't), better yet, create
a PR on GitHub.
> Documentation Bug: CollectionUtils.select(Iterable, Predicate, Collection,
> Collection), CollectionUtils.selectRejected(Iterable, Predicate, Collection)
> -------------------------------------------------------------------------------------------------------------------------------------------------------

> Key: COLLECTIONS-861
> URL: https://issues.apache.org/jira/browse/COLLECTIONS-861
> Project: Commons Collections
> Issue Type: Bug
> Reporter: Daniele
> Priority: Minor
>
> *CollectionUtils.select(Iterable, Predicate, Collection, Collection):*
> A ConcurrentModificationException can be thrown, but not described in the
> specification, also "return the outputCollection" is ambiguous because
> outputCollection is a parameter and it seems like the method should return
> that parameter as it is, but in is modified inside the method.
> *Test used:*
> {code:java}
> public class CollectionUtils_12_failure_Test extends
> CollectionUtils_12_failure_Test_scaffolding {
> public void testSelect_OutputCollection() throws Throwable {
> PriorityQueue<Object> priorityQueue0 = new
> PriorityQueue<Object>(comparator0);
> UniquePredicate<Object> uniquePredicate0 = new
> UniquePredicate<Object>();
> try {
> java.util.Collection<?> _methodResult__ =
> CollectionUtils.select((Iterable<?>) priorityQueue0,
> (Predicate<? super Object>) uniquePredicate0,
> (Collection<Object>) priorityQueue0,
> (Collection<Object>) priorityQueue0);
>
> org.junit.Assert.assertTrue(_methodResult__.equals(((Collection<Object>)
> priorityQueue0)));
> //** Postcondition on which the oracle of method select depends:
> methodResultID.equals(args[2])
> } catch (ConcurrentModificationException e) {
> verifyException("java.util.PriorityQueue$Itr", e);
> org.junit.Assert.fail();
