-----------------------------------------------------------------
Just to help you understand the problem: there are two different APIs to use
iterators in UIMA. Here the helper class makes use of both. This is generally a
bad idea because there's no guarantee the iterator won't break. Here however
it's a straight up error in integrity checking: it's not even a compatibility
issue between the two APIs.
Thanks for looking into this :)

> POSTagger UIMA AE broken because of AnnotationComboIterator
> -----------------------------------------------------------
>
> Key: OPENNLP-676
> URL: https://issues.apache.org/jira/browse/OPENNLP-676
> Project: OpenNLP
> Issue Type: Bug
> Components: POS Tagger, UIMA Integration
> Affects Versions: tools-1.5.3
> Environment: Oracle JDK8, Debian Jessie 64b
> Reporter: Hugo Mougard
> Assignee: Joern Kottmann
> Fix For: 1.6.0
>
>
> The AnnotationComboIterator helper class used by the UIMA POSTagger accesses
> its iterators unsafely.
> The consequence is that the AE breaks even on very simple CASes such as the
> CAS showcased on this repository (text of 9 letters, 2 sentence annotations
> and 9 token annotations):
> https://github.com/m09/postagger-iterator-bug/blob/master/in.xmi
> The repository linked above contains an example program that crashes on my
> setup. It's fully maven 3 aware so you can normally launch it quite easily.
> Here is a patch that should address the issue:
> https://raw.githubusercontent.com/m09/postagger-iterator-bug/master/iterator.patch
