It turns out my service class has a map property that doesn't use an interface. For example, Map<String, MyCustomClass>. I changed it to an interface: Map<String, ICustomClass>. (Of course you need to create the interface which is trivial).
On my VersionService, I have an animalDAOMap property declared as
<bean id="versionService" class="my.service.VersionService"
<entry key="dog" value-ref="dogDAO"/>
<entry key="cat" value-ref="catDAO"/>
<entry key="monkey" value-ref="monkeyDAO"/>
CustomDAO is not an interface! This works fine but when applying AOP, I get the error. Solution: You must convert the CustomDAO to an interface!
private Map animalDAOMap<String, CustomDAO>
