+	 * A change is made to an aspect on the aspectpath (staticinitialization() advice is added) for another project.
+	 * <p>
+	 * Managing the aspectpath is hard. We want to do a minimal build of this project which means recognizing what kind of changes
+	 * have occurred on the aspectpath. Was it a regular class or an aspect? Was it a structural change to that aspect?
+	 * <p>
+	 * The filenames for .class files created that contain aspects is stored in the AjState.aspectClassFiles field. When a change is
+	 * detected we can see who was managing the location where the change occurred and ask them if the .class file contained an
+	 * aspect. Right now a change detected like this will cause a full build. We might improve the detection logic here but it isn't
+	 * trivial:
+	 * <ul>
+	 * <li>Around advice is inlined. Changing the body of an around advice would not normally be thought of as a structural change
+	 * (as it does not change the signature of the class) but due to inlining it is a change we would need to pay attention to as it
+	 * will affect types previously woven with that advice.
+	 * <li>Annotation style aspects include pointcuts in strings. Changes to these are considered non-structural but clearly they do
+	 * affect what might be woven.
+	 * </ul>
