Hugo Mougard updated OPENNLP-676:
---------------------------------
Description:
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.
was:
The AnnotationComboIterator helper class used by the UIMA POSTagger uses both
UIMA & Java style iterators. This is strongly discouraged:
