Re: [aspectj-users] Pointcut not matching when using Generics

[Andy Clement <andrew.clement@xxxxxxxxx>]

Your two programs just compiled fine for me:

N:\aspectj168>ajc -showWeaveInfo -1.5 Main.java Captures.java
Join point 'method-execution(java.util.List Main.doS())' in Type
'Main' (Main.java:5) advised by around advice from 'Captures'
(Captures.java:12)

What version of AspectJ are you on?  (I am using 1.6.8).  I presume
you are compiling on the command line (as you are using showWeaveInfo)
- how does your compile command differ from mine?
