Re: [aspectj-users] Customized annotations @AspectJ vs AspectJ

[Andy Clement <andrew.clement@xxxxxxxxx>]

I didn't write that area of the code but I believe whatever route you
use to define the aspect, if it is compiled with ajc, the AspectJ
annotations will be added and that enables the AspectJ reflection
interface to work (AjType/etc).

As Wim says, make sure your annotations are of appropriate retention,
raise a bug if they are still discarded.
