フレックスアリタスクのフレックスコンパイラエラー（警告）メッセージ

Question

フレックスプロジェクトからフレックスsdkのantタスクを使用してコンパイルすると、次の警告が表示されます。誰にもこれがどこから来たのか、なぜこれが起きるのか、そして私がそれを無視してもいいのかというアイデアはありますか？

Answer 1

（swfファイル自体は、実際のエラーなしで作成されますように思われる）これらのバックトレースは本当にフレックスやアリとは何の関係もありません。それは実際にはAWTとXCBの間の相互作用に過ぎません。 sun bug 6532373またはXlib bug 11390で詳細を確認できます。 回避方法がありますが、必要ではないと思います（これらの不快なメッセージを削除する以外に）。
