Assuming my current package structure in a spring projects as :

```
com.stackoverflow
|- service
|- entities
|- controllers
   |- package1
   |- package2
|-util

```

How can I apply an aspect to all the packages under com.stackoverflow except on the package util?

Applying it to everything, the execution expression would be "com.stackoverflow..*.*(..)"

What should the execution expression be in this case I want to remove the util subpackage from the execution expression?
