> selectPreceding() does not return preceding for last annotation

> Key: UIMA-3403
> URL: https://issues.apache.org/jira/browse/UIMA-3403
> Project: UIMA
> Issue Type: Bug
> Components: uimaFIT
> Affects Versions: 2.0.0uimaFIT
> Reporter: Torsten Zesch
> Fix For: 2.0.1uimaFIT
>
>
> selectPreceding() does not return the preceding element for the last element
> in the CAS if one is looking for a different annotation type than the anchor.
> See the test below.
> If the anchor is a token and I want the preceding tokens, everything is fine,
> but when I use a token anchor to get the preceding lemmas, no lemma is
> returned for the last token in the CAS.
> Offset are exactly the same so the behaviour is unexpected.
> {noformat}
> @Test
> public void test()
> throws Exception
> {
> String testDocument = "This is a test document .\nIt is quite short
> .\n";
> AnalysisEngine engine =
> AnalysisEngineFactory.createEngine(NoOpAnnotator.class);
> JCas jcas = engine.newJCas();
> TokenBuilder<Token, Sentence> tb = TokenBuilder.create(Token.class,
> Sentence.class);
> tb.buildTokens(jcas, testDocument);
> engine.process(jcas);
>
> for (Token token : JCasUtil.select(jcas, Token.class)) {
> Lemma lemma = new Lemma(jcas, token.getBegin(), token.getEnd());
> lemma.addToIndexes();
> }
> for (Token token : JCasUtil.select(jcas, Token.class)) {
> // try {
> // List<Token> previous =
> JCasUtil.selectPreceding(Token.class, token, 1);
> // System.out.println(previous.get(0).getCoveredText());
> // }
> // catch (IndexOutOfBoundsException e) {
> // System.out.println(token);
> // }
> try {
> List<Lemma> previous = JCasUtil.selectPreceding(Lemma.class,
> token, 1);
> System.out.println(previous.get(0).getCoveredText());

> catch (IndexOutOfBoundsException e) {
