Code trying to ensure reverse iterators list items in the opposite order of
forward ones is present but not working
-------------------------------------------------------------------------------------------------------------------
Key: UIMA-1365
URL: https://issues.apache.org/jira/browse/UIMA-1365
Project: UIMA
Issue Type: Bug
Components: Core Java Framework
Reporter: Branimir Lambov
Priority: Minor
FSIndexRepositoryImpl contains pieces of code that are meant to ensure forward
and reverse iterators are inverses of each other by doing additional comparison
by FS address to resolve equality. However, this is not fully implemented and
isn't working properly.
The iteratorComparator defined by the PointerIterator class is not used for
sorting elements in moveToNext() and moveToPrevious(), where the default
comparators for the iterators are used instead. For the typical use of
PointerIterator of listing the annotation index this does not cause a problem
as the type priorities ensure ordering between indexes of different types,
while the ordering is always defined within the individual indexes.
The piece of code implementing the extra comparison should either be removed or
corrected.
