Re: [aspectj-users] Prodution Aspect - Exceptions

[Wes Isberg <wes@xxxxxxxxxxxxxx>]

Your pointcut picks out Error, but your test throws Exception.  

Your advice is:

   after() throwing (Error e): publicMethodCall() { 

Your test code is:

    public void throwError() throws Exception {
        throw new Exception("Teste");
    }

but it should be:

    public void throwError() {
        throw new Error("Teste");
    }

(This mistake is interesting because I can't think of an easy way to 
check for it. hmm.)

Thanks for the test cases -
Wes

P.S. - It was great that you send a complete test case with explanation
of each file.  You might have gotten a quicker response if you appended
the code to the email (rather than attached in separate files), esp. if
you can reduce it to one file.  Many list readers would have caught the 
mistake by inspection if they looked at the code, which I believe they
would have if it were reduced and inlined.
