[aspectj-users] How to exclude an anonymous inner method from a pointcut

[Ian Worthington <IanWorthington@xxxxxxx>]

I have an AspectJ trace routine set up to log method entry and exit 
conditions using the following pointcuts:

    public aspect Trace {
        pointcut anyMethodExecuted():       execution (* 
biz.ianw.lanchecker.*.*(..)) && !within(Trace); // && !within( 
is(AnonymousType) );
        pointcut anyConstructorExecuted():  execution 
(biz.ianw.lanchecker.*.new(..)) && !within(Trace);


In my email class I have a method which calls the setDebugOut method to 
redirect the debug output to a LogOutputStream:

    final private static  Logger log = 
LoggerFactory.getLogger(MailMail.class);
    ...
    LogOutputStream losStdOut = new LogOutputStream() {
        @Override
        protected void processLine(String line, int level) {
            log.debug(line);
        }
    };

    public void sendPlainHtmlMessage(...) {
        Session session = javaMailSender.getSession();
        PrintStream printStreamLOS = new PrintStream(losStdOut);
        session.setDebugOut(printStreamLOS);
        ...

This works fine, except that the Trace class pointcut intercepts the 
call to, presumably, the anonymous inner class, producing as output:

    20:14:18.908 TRACE [biz.ianw.lanchecker.Trace] - Enters method: 
Logger biz.ianw.lanchecker.MailMail.access$0()
    20:14:18.909 TRACE [biz.ianw.lanchecker.Trace] - Exits method: 
Logger biz.ianw.lanchecker.MailMail.access$0().
    20:14:18.909 TRACE [biz.ianw.lanchecker.Trace] -   with return 
value: Logger[biz.ianw.lanchecker.MailMail]
    20:14:18.909 DEBUG [biz.ianw.lanchecker.MailMail] - DEBUG: 
getProvider() returning 
javax.mail.Provider[TRANSPORT,smtp,com.sun.mail.smtp.SMTPTransport,Oracle]

I added the rather overly broad

    && !within( is(AnonymousType) )

condition to the pointcut, as shown above, but it had no effect. In fact 
I'm having real difficulty finding is(AnonymousType) documented anywhere.

How can I write a pointcut that excludes this anonymous inner method, 
preferably without impacting any others I may wish to log in future?
