JBoss AS 7
A slimmed down version of JBoss AS 7 (jboss-as) is now packaged for Fedora. JBoss AS 7 is a fast, modular, lightweight, compliant Java EE application server. Currently only the JBoss AS 7 Web Profile is supported, support for the Full Profile will be added in a later release.
OpenJDK7 is now the default Java Development Kit in Fedora, replacing OpenJDK6. A full list of the features added in OpenJDK7 is available upstream at http://openjdk.java.net/projects/jdk7/features/.
