Marco,

You may only throw checked exceptions in advice that are thrown by the advised join point. This isn't considered bad practice as you may refactor logic in a method that throws an exception into an aspect. I suspect the problem that you are seeing, which disappears with a full build, is related to incremental compilation.

Re: [aspectj-users] Exception handling in aspects / RAD/Aspectj







hello fernando,
 yes it is... but i was wondering if in general it was a bad practice to raise exception from advices (even when  the intercepted method throws the same exception)..

thanx and regards
marco

Marco,

Is MyException in the 'throws' clause of the intercepted method? If it
is not and MyException is a checked exception (does not inherit,
directly or indirectly, from RuntimeException), the compiler should
complain.

Regards,
Fernando
