Martin Wiesner reopened OPENNLP-1471:
-------------------------------------
> Ensure Dictionary#asStringSet() implements hashCode() and equals() correctly
> ----------------------------------------------------------------------------
>
> Key: OPENNLP-1471
> URL: https://issues.apache.org/jira/browse/OPENNLP-1471
> Project: OpenNLP
> Issue Type: Improvement
> Affects Versions: 2.1.0, 2.1.1
> Reporter: Martin Wiesner
> Assignee: Martin Wiesner
> Priority: Minor
>
> The tests (a) {{DictionaryAsSetCaseInsensitiveTest}} and
> {{(b) DictionaryAsSetCaseSensitiveTest}} have an open TODO that points to a
> bug in Dictionary#asStringSet()
>
> {quote}// TODO: should it be equal??
> Assertions.assertNotSame(setA.hashCode(), setB.hashCode());
> {quote}
> To cure this, the implementation of Dictionary#asStringSet() needs override
> hashCode and equals properly.
> After fixing the implementation, the following assertion must hold:
> {quote}Assertions.assertEquals(setA, setB);
> Assertions.assertEquals(setA.hashCode(), setB.hashCode());
> {quote}
> where setA and setB are obtained via {{{}Dictionary#asStringSet(){}}}.
