http://nagoya.apache.org/bugzilla/show_bug.cgi?id=25154 IteratorChain bug with empty iterators. Summary: IteratorChain bug with empty iterators. Product: Commons Version: 2.1 Final Platform: All OS/Version: All Status: NEW Severity: Normal Priority: Other Component: Collections AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Haven't tried this with nightly builds, but 2.1 collections have the follwoing problem: when the first iterator in a chain is empty, first call to "hasNext" returns false, on second and subsequent calls, "true" is returned again as it should. Here is an example: List emptyList = new ArrayList(); List nonEmptyList = new ArrayList(); nonEmptyList.add(new Object()); IteratorChain it = new IteratorChain(new Iterator[] {emptyList.iterator(), nonEmptyList.iterator()}); System.out.println("Next? " + it.hasNext()); // prints false System.out.println("Next again? " + it.hasNext()); // prints true Cheers, Andrus --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
