             Summary: `between` throws an exception for zero-width annotations
                 Key: UIMA-5829
                 URL: https://issues.apache.org/jira/browse/UIMA-5829
             Project: UIMA
          Issue Type: Bug
          Components: UIMA
    Affects Versions: 3.0.0SDK
            Reporter: Richard Eckart de Castilho


SelectFS throws an exception in the following case. Why not return an empty 
list?

{code}
    Token t1 = new Token(jCas, 45, 57);
    t1.addToIndexes();
    Token t2 = new Token(jCas, 52, 52);
    t2.addToIndexes();

    new Sentence(jCas, 52, 52).addToIndexes();

    // uimaFIT: selectBetween(jCas, Sentence.class, t1, t2);
    List<Sentence> stem1 = jCas.select(Sentence.class).between(t1, t2).asList();
    assertTrue(stem1.isEmpty());
{code}

{code}
java.lang.IllegalArgumentException: End value must be >= Begin value
