Also recently, The AspectJ and AspectWerkz projects have agreed to work together as one team to produce a single aspect-oriented programming platform building on their complementary strengths and expertise. The first release from this collaboration will be AspectJ 5, which extends the AspectJ language to support an annotation-based development style in addition to the familiar AspectJ code-based style. AspectJ 5 will also provide full AOP support for the new Java 5 language features.
According to Alex Vasseur and Jonas,
You can now use this final version while beeing on the starting block for the upcoming versions of AspectJ 5 that will include support for our annotation defined aspect as well as similar load time weaving capabilities, among others, making the transition as smooth as possible.AspectWerkz 2.0 articles/tutorials on TSS:
