Re: [aspectj-dev] How to resolve method binding in advice declaration
|
We know the AspectJ Ast is incomplete. As users need features from it,
it is extended to handle them. Sometimes the user who needs the new
feature implements it and adds it as a patch to a bugzilla report.
For example: https://bugs.eclipse.org/bugs/show_bug.cgi?id=168714 or
https://bugs.eclipse.org/bugs/show_bug.cgi?id=110465
You should at least raise a bug for this, but it's more likely to get
into the codebase if you also supply an implementation ;)
