**Android Platform API Version 22**

まず、Android Platform API 22 で androidx.work.impl.WorkDatabase.onOpen、androidx.sqlite.db.framework.FrameworkSQLiteDatabase.endTransaction、androidx.work.impl.utils.ForceStopRunnable を通る報告されたパスを追跡します。issue には再現手順も期待される動作も記載されていないため、最初にトリガーとなるデータベースの状態を明らかにし、完了条件をこの rollback 例外を防止するか正しく処理することと定義します。
