Re: [ajdt-dev] Advice, raising different exceptions depending on 'pointc

["iyad issa" <iyadissa@xxxxxxxxx>]

you can do this

void around():execution( void *.setData(..)){
            try{
                proceed();
           }catch(Throwable raisedExc){
               throw new ConcernRuntimeException(raisedExc)
           }
}

p.s you can only do this if ConcernRuntimeException is a RuntimeException
