RE: [aspectj-users] What a class is not found?

[Jim.Hugunin@xxxxxxxx]

I'd strongly suggest you change your aspect to use:

  after() returning: allMethodsCut()
instead of
  after(): allMethodsCut()

(Yes, I know this is from the example code.  I also think the example code needs to be changed.)

Just like finally clauses in Java, straight after advice can sometimes do strange things to exception traces by replacing one with another.  For a little more about after and finally, see the FAQ at:
