[jira] [Updated] (UIMA-6297) SelectFS with limit in combination with fsIterator has issues

["Richard Eckart de Castilho (Jira)" <de...@uima.apache.org>]

Richard Eckart de Castilho updated UIMA-6297:
---------------------------------------------
    Description: 
When doing a SelectFS.limit(x).fsIterator(), then an iterator is returned which can only call get() x times. Moving the iterator around (moveToNext, moveToPrev, etc.) is not really taken into account. This could be considered a bug e.g. in situations such as this:

{code}
FSIterator i = cas.select().following(x).limit(2).fsIterator();
i.get(); // first result
i.moveToNext();
i.get(); // second result
i.moveToPrevious();
i.get() // Expected: first result -- actual: NoSuchElementException
{code}
