java.lang.Object
org.aspectj.lang.Aspects14
For users working on a level of Java prior to Java5, Aspects14 handles generic aspectOf methods when they
are not available in the aspects but added later on through load time weaving. Users on Java5 should use
the class Aspects instead.
Aspects14.aspectOf(..) is doing reflective calls to the aspect aspectOf, so for better performance
consider using ajc compilation of the aspects and using them as a binary dependencies in your project.
