  1. Integrating Load-Time Weaving into OSGi Matthew Webster IBM Java Technology Hursley, UK AspectJ Committer Martin Lippert Consultant it-agile

  2. Goals • Provide Runtime Modularity and Versioning for Crosscutting Concerns • Declarative configuration of cross cutting concerns at the bundle level • Opt-in and co-opt models • Raise the level of abstraction for an AOP: develop, consume and deploy cross-cutting capability as bundles and fragments • Facilitate the Independent Delivery of Crosscutting Capability • Cross-cutting capability delivered separately from core function • Flexible approach to consuming platform features • Re-use at binary bundle level • Simplify Load-Time Weaving • Weaving determined by bundle dependencies • Weaving scoped by bundles • Weaving mechanism is JVM-independent
