aspect

The AspectJ weaver applies aspects to Java classes. It can be used as a Java agent in order to apply load-time weaving (LTW) during class-loading and also contains the AspectJ runtime classes.

Spring AOP provides an Alliance-compliant aspect-oriented programming implementation allowing you to define method interceptors and pointcuts to cleanly decouple code that implements functionality that should be separated.

Starter for aspect-oriented programming with Spring AOP and AspectJ

The AspectJ runtime is a small library necessary to run Java programs enhanced by AspectJ aspects during a previous compile-time or post-compile-time (binary weaving) build step.

Spring Aspects integrates Spring with AspectJ.

AOP Alliance

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.

The byteman jar merges the byteman-agent jar contents with those of the byteman-jigsaw and byteman-layer jars as a mutli-release jar. The contents of the latter two jars are installed under META-INF/versions/9 ensuring that they are only linked when Byteman is deployed on a JDK9+ JVM
