Java 7 was released with a JIT compiler bug. This should not be an issue for the Java performance community - if you have a performance problem, you haven't been waiting for Java 7 to fix it for you, you've been busy analysing and fixing it yourself; and if you don't have any performance problems, you aren't about to upgrade your productions systems to Java 7 on the very first release!

What we Java performance bods can now do though, with Java 7 now fully out, is start to see which features and options are useful. There are some interesting things in there: Sockets direct protocol, asynchronous file handling, the G1 collector, ... (see the release notes for more details). If you've been a reader of our newsletter then you've already read about many of the new features, but I'm sure some other interesting new things will get identified now the new JVM is out there and used by lots more people. Of course you can read all about anything useful for performance in our future newsletters.

So on with this month's newsletter and all our usual Java performance tools, news, and article links. We also have a new cartoon over at fasterj.com Sizing the generations is the most important tuning option, and, as usual, all the extracted tips from all of this month's referenced articles. Usually, one or two of the extracted tips leap out as gems which I highlight in the RSS feed, but this month there is a host of fabulous tips - enjoy!
