--------------------------------------
Is there an earlier Jira for this issue? (I may have missed it...; given that
you've noticed this and had put in a work-around)
> moveTo(fs) where fs > all items in index is broken
> --------------------------------------------------
>
> Key: UIMA-4094
> URL: https://issues.apache.org/jira/browse/UIMA-4094
> Project: UIMA
> Issue Type: Bug
> Components: Core Java Framework
> Affects Versions: 2.4.0SDK, 2.4.1SDK, 2.4.2SDK, 2.5.0SDK, 2.6.0SDK
> Reporter: Marshall Schor
> Assignee: Marshall Schor
> Fix For: 2.6.1SDK
>
>
> Using moveTo(fs) where the fs is beyond the last element in the index
> incorrectly sets the iterator position to the 1st element. It should set the
> iterator to (from the Javadocs) ""insertion point" for fs, i.e., to a point
> where the feature structure at that position is greater than fs and the fs at
> the previous position (if it exists) is less than fs
> When the fs is > all the elements in the index should conceptually set the
> iterator to 1 past the end of the index, which isValid() will return "false"
> for.
> Because this change may break user code (in case users have worked around
> this), I think this change should be removable under a JVM property flag,
> something like uima.keep_wrong_moveTo_behavior.
> UIMA-1601 introduced this behavior (8/19/2011).
