Glassfish Roadmap and Java SE 6 Update
Oracle announced some details on the future of Glassfish. In a nutshell, Oracle will continue developing Glasfish as open-source, clustering will be included, it will continue to be a full-featured Java EE 6 implementation, there will be some degree of integration with Oracle Fusion, and it will run on both the Hotspot and JRockit JVMs. Oracle will also maintain the ";100 day"; release schedule for versions 2.1.2 and 3.0.1, with version 3.1 coming later this year.
Java SE 6 Update 20 was released this week with some critical bug and security fixes. Oracle strongly recommends that Java SE 6 users upgrade to this release. For more information on the security issues fixed, check out this recent US-CERT notification.
