738:, so developers could write aspects for code in binary (.class) form. At this time the AspectJ language was restricted to support a per-class model essential for incremental compilation and load-time weaving. This made IDE integrations as responsive as their Java counterparts, and it let developers deploy aspects without altering the build process. This led to increased adoption, as AspectJ became usable for impatient Java programmers and enterprise-level deployments. Since then, the Eclipse team has increased performance and correctness, upgraded the AspectJ language to support

730:. In all cases, the AspectJ program becomes a valid Java program that runs in a Java VM. Classes affected by aspects are binary-compatible with unaffected classes (to remain compatible with classes compiled with the unaffected originals). Supporting multiple implementations allows the language to grow as technology changes, and being Java-compatible ensures platform availability.
869:. After Adrian Colyer, Andrew Clement took over as project lead and main contributor for AspectJ. AJDT has since been retired as a separate project and taken over into the Eclipse AspectJ umbrella project to streamline maintenance. However, both AspectJ and AJDT are still maintained in separate source repositories.

Key to its success has been engineering and language decisions that make the language usable and programs deployable. The original Xerox AspectJ implementation used source weaving, which required access to source code. When Xerox contributed the code to
Eclipse, AspectJ was reimplemented using the
