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

/**
 * For implementing declare @type interacting with declare @parents during compilation - we need to be able to add an annotation to
 * 'binary type binding' (this is how types are seen during incremental compilation). Unlike a SourceTypeBinding - a
 * BinaryTypeBinding does not allow easy interaction with its annotations - so what we do is take the eclipse annotation, suck out
 * the name/signature and visibility and put that information in a 'FakeAnnotation'. The FakeAnnotation is attached to the BCEL
 * delegate for the binary type binding - this will allow type resolution to succeed correctly. The FakeAnnotation never makes it to
 * disk, since the weaver does the job properly, attaching a real annotation.
