Sorry I didn’t see it on StackOverflow - I do hang around there too when I can!
The access$0 method has been added to MailMail because log is private in
MailMail - it enables the log.debug(line) to access log from the anonymous
class (presumably called MailMail$1).
Recognizing that, we can see that access$0 is not in the anonymous class, it is
an accessor generated in the MailMail class, hence your additional pointcut
fragment not working.
Couple of options:
Exclude it specifically:
pointcut anyMethodExecuted(): execution (*
biz.ianw.lanchecker.*.*(..)) && !within(Trace) && !execution(*
MailMail.access$0(..));
Exclude all synthetic accessors (it is considered synthetic because it is
‘generated’ by the compiler to support what you are doing):
pointcut anyMethodExecuted(): execution (*
biz.ianw.lanchecker.*.*(..)) && !within(Trace) && !execution(synthetic *
access$*(..));
Or you could exclude all synthetics perhaps:
pointcut anyMethodExecuted(): execution (!synthetic *
biz.ianw.lanchecker.*.*(..)) && !within(Trace);
cheers,
