-------------------------------------------
I should have some over the weekend to fix it, though it would go into trunk
and the next release.
> SpellChecker finaliser calls close regardless of if closed already
> ------------------------------------------------------------------
>
> Key: LUCENENET-443
> URL: https://issues.apache.org/jira/browse/LUCENENET-443
> Project: Lucene.Net
> Issue Type: Improvement
> Components: Lucene.Net Contrib
> Affects Versions: Lucene.Net 2.9.2
> Reporter: Stuart Robinson
> Labels: lucene, spellcheck, spellchecker
>
> The SpellChecker Class currently has no publicly visible way of accessing the
> closed field. It also calls close in the finaliser killing the process it is
> in upon GC as this can throw an exceptin. I propose two changes:
> Change the already existing method "IsClosed()" to public:
> public bool IsClosed()
> {
> return closed;
> }
> and add a check on this in the finaliser:
> ~SpellChecker()
> {
> if (!IsClosed())
> this.Close();
> }
> Ideally this class should implement IDisposable but I think this would be a
> bigger job than this two line change.
