How to re-throw exception in AspectJ around advise

Question

I have some methods which throws some exception, and I want to use AspectJ around advise to calculate the execution time and if some exception is thrown and to log into error lo

Answer 1

There is an "ugly" workaround - I found them in Spring4 AbstractTransactionAspect

Object around(...): ... {
    try {
        return proceed(...);
    }
    catch (RuntimeException ex) {
        throw ex;
    }
    catch (Error err) {
        throw err;
    }
    catch (Throwable thr) {
        Rethrower.rethrow(thr);
        throw new IllegalStateException("Should never get here", thr);
    }
}

/**
 * Ugly but safe workaround: We need to be able to propagate checked exceptions,
 * despite AspectJ around advice supporting specifically declared exceptions only.
 */
private static class Rethrower {

    public static void rethrow(final Throwable exception) {
        class CheckedExceptionRethrower {
            @SuppressWarnings("unchecked")
            private void rethrow(Throwable exception) throws T {
                throw (T) exception;
            }
        }
        new CheckedExceptionRethrower().rethrow(exception);
    }
}
