AspectJ tools most notably contains the AspectJ compiler (AJC). AJC applies aspects to Java classes during compilation, fully replacing Javac for plain Java classes and also compiling native AspectJ or annotation-based @AspectJ syntax. Furthermore, AJC can weave aspects into existing class files in a post-compile binary weaving step. This library is a superset of AspectJ weaver and hence also of AspectJ runtime.

There is a newer version: 1.9.22.1

/**
 * A {@code BundleEvent} listener. {@code BundleListener} is a listener
 * interface that may be implemented by a bundle developer. When a
 * {@code BundleEvent} is fired, it is asynchronously delivered to a
 * {@code BundleListener}. The Framework delivers {@code BundleEvent} objects to
 * a {@code BundleListener} in order and must not concurrently call a
 * {@code BundleListener}.
 * 
 * A {@code BundleListener} object is registered with the Framework using the
 * {@link BundleContext#addBundleListener(BundleListener)} method.
 * {@code BundleListener}s are called with a {@code BundleEvent} object when a
 * bundle has been installed, resolved, started, stopped, updated, unresolved,
 * or uninstalled.
