Project Plan For AspectJ, version 1.0

Introduction

AspectJ major versions match up with Java versions. Currently Java is at 1.7 and AspectJ is about to release the 1.7 version after 13 releases at 1.6 (1.6.0 -> 1.6.12). The AspectJ project then releases service refreshes to that major version every few months. The current release model is at least something every 3 months - sometimes a milestone, sometimes a full release.
AspectJ always maintains that HEAD will build clean and pass all the tests we have (currently around 4400). This means the development builds created from HEAD after every commit are always at least as good as the previous build.

Release Deliverables

AspectJ releases are delivered as a single .jar download that installs a compiler and the related tools and documentation when executed. The packaging of an AspectJ release into plugins consumable in an Eclipse environment is done by the AJDT project.

Target Environments

During AspectJ 1.6.6 development the decision was made to exploit generics internally and this has improved the quality of the codebase. However, this means the 1.6.6 weaver (and therefore compiler) now require a Java 1.5 runtime. Previous versions of AspectJ required only Java 1.4
The woven code produced by AspectJ will run on any VM from Java 1.3 onwards.
The compiler/weaver will run on 1.5 but with AspectJ 1.7 these have the ability to compile 1.7 source code (using 1.7 features like the diamond operator) or weave into 1.7 bytecode that is exploiting new bytecode features like invokedynamic.

Internationalization

We have bundles for many of the messages in the project but they are not translated.

Compatibility with Previous Releases

AspectJ is strong on compatibility and any level of AspectJ is always intended to parse code/aspects built with any earlier version of AspectJ without requiring recompilation.

Themes and Priorities

These are the larger themes and priorities right now:

Improving the IDE experience

This is about maintaining an expected level of functionality and responsiveness when a user switches from a Java project to an AspectJ project. The latest requirement in this area is the need to persist project state between eclipse restarts - otherwise a costly full build is necessary each time eclipse is started. This is *not* easy as the object graph after a build is not currently of the right form to persist.

Memory Usage

Improving it across all parts of AspectJ: compilation, weaving and load-time weaving.

Groovy weaving

Given the popularity of groovy, these enhancements cover coping with weaving groovy class files
