handling a specific exception type

I've defined two AfterThrowing advices to handle exceptions with the same pointcut.

@AfterThrowing(pointcut="...", throwing="ex")
public void method1(Exception ex) {}


@AfterThrowing(pointcut="...", throwing="ex")
public void method2(GatewayException ex) {}

Is there a way for me to prevent the generic method1 being executed if the exception is a GatewayException?

Any ideas greatly appreciated

It would be the easiest to check the instance of the exception inside the advice body and return early if it's of the more specific exception type:

@AfterThrowing(pointcut="...", throwing="ex")
public void method1(Exception ex) {
    if (ex instanceof GatewayException) {
        return;
    }
    // handle the more generic Exception case
}


@AfterThrowing(pointcut="...", throwing="ex")
public void method2(GatewayException ex) {
    // handle the more specific GatewayException
}

I know you expected a solution based on some AspectJ language construct, but the thing is, there's no such construct.
