The distribution of an optimising, extensible compiler for AspectJ, freely available under the LGPL. The abc project is a joint effort between the University of Oxford (UK), McGill University (Canada), and the University of Aarhus (Denmark). [Open sou...
Dynamic, lightweight and high-performing AOP framework for Java; uses bytecode modification to weave classes at project build-, class-load-, or run-time. [Open Source, LGPL]
Paper that introduces the Java-based language Sally and compares it with AspectJ: interactions as opposed to method entry, named advice, advice overriding. Also compares aspects, conventional inheritance, and mixins.
Very small and fast Java bytecode manipulation framework; can be used to dynamically generate stub classes or other proxy classes, directly in binary form, or to dynamically modify classes at load time, just before loaded into a JVM. [Open Source, BSD]
Helps enforce architectural rules (layering, tiering, and modularity) in Java code. It applies pattern-based access rules from XML rules files to compiled classes. [Open source, GPL]
PROgrammable extenSions of sErvices; allows modifying Java programs at run-time; dynamic aspect-oriented programming (AOP), adaptive service architectures, and information systems for mobile computing.
