Simon Willnauer updated LUCENE-1817:
------------------------------------

    Attachment: LUCENE-1817-mark-cn-experimental.patch

We should mark the smartcn module  experimental as we plan to do heavy refactoring after 2.9 is out. This patch adds a notice to package.html and JavaDoc.
Quoting Mark Miller from the list:
bq. Warning users that you don't plan on promising back compat with experimental warnings seems like a good idea to me.

> it is not possible to use a custom dictionary, even though there is a lot of code and javadocs to allow this.
> This is because the custom dictionary is only loaded if it cannot load the built-in one (which is of course, in the jar file and should load)
> {code}
> public synchronized static WordDictionary getInstance() {
>     if (singleInstance == null) {
>       singleInstance = new WordDictionary(); // load from jar file
>       try {
>         singleInstance.load();
>       } catch (IOException e) { // loading from jar file must fail before it checks the AnalyzerProfile (where this can be configured)
>         String wordDictRoot = AnalyzerProfile.ANALYSIS_DATA_DIR;
>         singleInstance.load(wordDictRoot);
>       } catch (ClassNotFoundException e) {
>         throw new RuntimeException(e);
>       }
>     }
>     return singleInstance;
>   }
> {code}
> I think we should either correct this, document this, or disable custom dictionary support...
