jRuby錯誤 - 無法修改凍結數組

Question

無論我嘗試解決什麼問題，我都會在應用程序中收到此錯誤。 「無法修改凍結陣列」

任何想法這裏可能有什麼錯誤？我在我的本地Ubuntu（10.04）機器上運行Torquebox（1.0.1）上的jRuby（1.6.2）應用程序。下面是一個完整的堆棧跟蹤

如果您在啓動過程中出現錯誤，機會是很大的，你實際上是試圖重新定義在初始化凍結陣列（可能是因爲redifining ABBR_DAYNAMES一樣簡單）。如果應用程序可以在MRI下運行，您可以嘗試一下，因爲它會爲您提供詳細的警告。

如果初始化程序中沒有任何內容，那麼它可能是您包含在應用程序中的寶石。嘗試一個一個地拿出寶石，看看結果是什麼。
