Re: [aspectj-dev] Annotation & Jdk1.4

[Alexandre Vasseur <avasseur@xxxxxxxxx>]

See
http://blogs.codehaus.org/people/avasseur/archives/001140_aspectj_5_load_time_weaving_with_java_13_using_aspectwerkz.html

for all these scenarios with java 1.3./1.4
- annotation defined aspect
- pointcut based on an annotation
- load time weaving for those use cases
