Here's one:

before() throws IOException: fileOp() {
    logStream = new FileOutputStream("log");
    ...
}

after() throwing (IOException ioe): fileOp() {
    handleException(ioe);
} 

If the after is more precedent, then it will act as if it is "outside" of the before and any exceptions thrown by the "new FileOutputStream" call will be seen by the after throwing advice.  However, if the after is less precedent, then it is "inside" the before and will not see any exceptions thrown by the before.
