[aspectj-users] Re: LTW and perthis/pertarget question...

[Paul Freeman <PaulFreeman@xxxxxxxxxx>]

Hi Matthew -

The perthis clause is specified as perthis(login()) where login is the a 
pointcut in the aspect LoginAspect that describes a method execution in 
the class KronosLoginModule.  KronosLoginModule was present in the 
application both during compile-time weaving and load-time weaving.

The information from the weaver seems to indicate that the 
afterReturning advice was properly woven during load-time, however it 
doesn't execute.  It will weave and execute under load-time weaving if I 
remove the perthis clause in the aspect declaration.  And it will weave 
and execute under compile-time weaving with the perthis clause included.

Thanks for responding.

Paul
