We're using deprecated methods and types from Apache Lucene; in most cases this is caused by the lack of better alternatives which we can't avoid w/o removing currently supported features, especially things exposed over our public API in version 5.8. In some internal cases this is avoidable and it would be a good time to reduce the amount of such cases, so that we're not overwhelmed by deprecation warnings and can still keep a critical eye on the reamining ones. |
