GUI を作成するための Netbeans 6.8 (Mac バージョン) ドラッグ アンド ドロップ ツールを使用して、プログラムが変更して表示するデータをユーザーが貼り付ける JTextArea を設計しました。
正常に動作しています。ただし、JTextArea に約 65,000 行のテスト データを貼り付けようとすると、GUI にはこれらの行の一部 (50 行以下など) しか表示されませんでした... 何らかの理由で、コピーしたテスト データ全体の貼り付けが拒否されました。メモ帳から。
JTextArea がいっぱいか何かだと思っていましたが、(テスト データを貼り付けた後) 手動でさらにテキストを入力しようとすると、テキスト ボックスに入力されて表示されていました。
何が起こっているのですか?

これは、私の GUI 用に netbeans によって自動的に生成されたコードです。
それで、修正する必要があるものはありますか?
