At the weekend I managed to get some free time away from working on our next release to look at a recent benchmark that compared the performance of Google Guice 1.0 with Spring 2.5. The benchmark referred to in the article as a modified version of Crazy Bob’s “Semi Useless” Benchmark is interesting not in terms of the results but in the analysis of the results and test construction. After reviewing the findings and benchmark code I thought it would be a good idea to instrument particular parts in the code with our Probes resource metering framework to better understand some peculiarities reported and to show how I use JXInsight Probes myself.... more »

Web 2.0 applications developed using standard Java Platform, Enterprise Edition 5 (Java EE)-based approaches face serious performance and scalability problems. The reason is that many principles that underlie the Java EE platform's design especially, the use of synchronous APIs don't apply to the requirements of Web 2.0 solutions. This article explains the disparity between the Java EE and Web 2.0 approaches, explores the benefits of asynchronous designs, and evaluates some solutions for developing asynchronous Web applications with the Java platform.... more »

The Closures for Java prototype now allows a closure to access mutated local variables from an enclosing scope. You can download the prototype here. You can also download the sources for the rewritten parts of Doug Lea's fork-join library, ported to use function types. It is a good example of how APIs can be affected by these language changes. Personally, I find the API simplifications to be quite compelling. If you're on the fence about function types, I recommend you have a look. Any feedback you may have is most welcome!... more »
