[Solr] JapanesePartOfSpeechStopFilterFactory : java.lang.ClassCastException: java.lang.String cannot be cast to [C

Solr で JapanesePartOfSpeechStopFilterFactory を使うように schema.xml を修正すると、java.lang.ClassCastException が発生してしまう。

解決方法は現在、調査中です。

HTTP ERROR 500

Problem accessing /solr/admin/. Reason:

    Severe errors in solr configuration.

Check your log files for more detailed information on what may be wrong.

If you want solr to continue after configuration errors, change: 

 false

in solr.xml
