CDDL (Common Development and Distribution License) とクラスパス例外付き GNU Public License v.2

NetBeans IDE 6.9.1 のコードの大部分は、CDDL (Common Development and Distribution License) v1.0 と GNU GPL (General Public License) v2 から構成されるデュアルライセンスに基づいて入手できます。NetBeans 内のコンポーネントの詳細と適用されるライセンスを参照してください。

NetBeans ソースの 5.5 リリースより前のバージョンは、Sun Public License に基づいて入手できるようになっていました。この変更の理由に関する考察は、ここに記載されています。

CDDL と初期の SPL の両方は MPL (Mozilla Public License) に基づいています。CDDL の方が再利用しやすいライセンスであり、読みやすく書かれています。どちらにも同じ特性があります。

  • それらに基づいてライセンスされたソースは、市販品で再利用される可能性があります
  • ソースに直接行われた変更 (バグ修正や機能拡張) は netbeans.org に返す必要がありますが、NetBeans のコードにリンクする、新たに書かれたソースファイルはその必要がありません

ソースファイルのライセンスについて

netbeans.org 上のソースファイルにはライセンスの全文は必要ありません。代わりに、それらがこのライセンスの下で保護されることを記述したヘッダーのみが必要です。ヘッダーには次のように書かれています (必要な注釈文字は無視します)。
