[jbosscache-dev] Announcing JBoss Cache 2.2.0 "Poblano"

Exciting news! 2.2.0.BETA1 has been released. This is a very interesting release for us, for a number of reasons: * Big architectural change for the internals, where each API method is implemented as a Command, which has the knowledge to perform and rollback. Does away with the monolithic CacheImpl class. * New interceptor structure means that implementations have strongly typed callbacks for each Command invoked. No more casting to get parameters, or switch statements based on MethodCall id. * Both of the above translate to a much more straightforward code base that is easier to read, modify and extend, but most importantly, unit test. * Still 100% backward compatible. And we have tests for this. Both on a wire protocol level (Marshallers know how to map Commands to old- style MethodCalls and vice versa) as for custom interceptor implementations (the old Interceptor class still exists, with a compatible invoke() method, and although deprecated now, still behaves the same way it used to and plays nice with the new framework) * No regressions when running with Hibernate trunk - need to verity with EJB3 and HTTP session repl. * A few new features implemented (see JIRA [1]), such as JBCACHE-1258 and JBCACHE-1320 * .... and, a nice surprise - some very tasty performance gains (in double digits)! Mircea will follow up this email with benchmark numbers and pretty pictures, sitting around a profiler sure pays off. :-) Download this and give it a try - this is a very big release for us, and as much feedback as early as possible would help. Check it out from SVN [2], check out the javadocs [3], and download and try out the release in your applications! It is not up on sourceforge yet, but it should go up shortly. In the meanwhile, you can grab the release from our maven2 repository [4]. Cheers Manik [1] http://jira.jboss.org/jira/secure/ConfigureReport.jspa?versions=12311704&...
