Zoom IntelliJ IDEA 9.0 on Mac OS X.
Version 9 of Java development environment IntelliJ IDEA has now been released in two variants – a commercial version, dubbed Ultimate Edition, and an open source Community Edition. The Apache 2.0 licence, which is also used by other JetBrains open source projects, has been selected for the Community Edition.

The open source version is available for Windows, Mac OS X and Linux and includes various refactoring, code inspection/help and debugging functions. The Community Edition still supports testing using TestNG and JUnit, version control systems CVS, Subversion and Git and build tools Maven and Ant.

The Ultimate Edition additionally supports web frameworks such as Spring 3 and Hibernate, more programming languages (e.g. PHP) and includes more deployment functions than the free open source version. It can be integrated into systems such as Perforce, Microsoft's Team Foundation Server and Rational ClearCase. Application development for Google's Android operating system and Adobe's Flex and AIR technologies are also supported.

The JetBrains website includes a comparison page showing the differences between the open source and Ultimate editions. According to the license fee page a Commercial License will set you back £450 and a Personal Licence can be acquired for £187. Other licenses are available by application for academic use or for non-commercial developers. Upgrades from version 8 can be obtained at a reduced price (Commercial £225, Personal £112) or free where the licence was acquired after 1st October 2009.

JetBrains, the company behind the IDE, announced its plan to release an open source version of the development environment in October. Following the demise of previously popular development environments such as Borland's JBuilder, OptimalJ and JDeveloper, which have all either been abandoned, made available for free, or open sourced and left to the Java community, IDEA, the number 3 in the Java IDE market behind open source projects Eclipse and NetBeans, had long been the only purely commercial player.
