> select following finds zero-width annotation at reference end position

> Key: UIMA-6286
> URL: https://issues.apache.org/jira/browse/UIMA-6286
> Project: UIMA
> Issue Type: Bug
> Components: Core Java Framework, uimaFIT
> Reporter: Richard Eckart de Castilho
> Assignee: Richard Eckart de Castilho
> Priority: Major
> Fix For: 2.5.0uimaFIT, 3.2.0uimaFIT, 3.2.0SDK
>
>
> The uimaFIT {{selectFollowing}} as well as the UIMA v3 {{SelectFS.following}}
> show the following behavior:
> * Given two annotations {{X: [0-1]}} and {{Y: [1-1]}}
> * performing an operation {{select annotations FOLLOWING X}}, {{Y}} is
> returned.
> So a zero-width annotation at the end of another annotation is treated to be
> "following" that other annotation.
> However, a zero-width annotation at the beginning of another annotation is
> NOT treated to be "preceding" that other annotation.
> * Given two annotations {{X: [1-2]}} and {{Y: [1-1]}}
> * performing an operation {{select annotations PRECEDING Y}}, {{X}} is not
> returned.
> Looking at the uimaFIT implementation, the fact that the SelectFS was
> modelled after the uimaFIT implementation and a general discussion on the
> mailing list regarding the rationales for interval predicates (e.g. following
> and preceding), I come to the conclusion that the uimaFIT selectFollowing was
> simply not thought to the end when it was implemented. So this seems to be an
> edge-case bug that needs to be fixed for a consistent behavior.
