Re: [aspectj-users] Re: A switch oddity
|
Hey, Matthew, thanks for the reply. So, basically, a final Java field
cannot be declared in AspectJ, right? For my application, I can always get
around. But I can't think of philosophically why aspects should be
prohibited from doing so. Could this be a bug or an intended behaviour?
Thanks again.
Charles
