Why does Sun want to dual license NetBeans under CDDL and GPLv2?
• The GPL v2.0 license will provide an additional option to vendors that are unable to work with NetBeans under the CDDL license. • Adding GPLv2 as a license option will make NetBeans even more Linux friendly. • Adding GPLv2 with Classpath exception to NetBeans will keep product portfolios and bundles consistent. Sun open sourced its JDK implementation under GPLv2 and the GlassFish project is dual-licensed under CDDL and GPLv2 with Classpath exception.
