Spring not autowiring a collection via the load-time weaver

Question

As per this question, it seems that you can declare something like the following and have it "work":

@Configurable(autowire=Autowire.BY_TYPE)
public class Target {

    private List<Dependency> dependencies;

    public List<Dependency> getDependencies() {
        return this.dependencies;
    }

    @Autowired
    public void setDependencies(List<Dependency> dependencies) {
        this.dependencies = dependencies;
    }
}

Application context:

<beans>
    <!-- where all extend Dependency -->
    <bean class="com.dependencies.SubDependency"/>
    <bean class="com.dependencies.SubSubDependency"/>
</beans>

According to the manual, this should "just work™", but it doesn't. Other dependenices are wired on Target but the list dependency isn't. Is there something I'm doing wrong? I only have one dependency at the moment to be wired, but this will expand with time.

I've got an example of doing this with build-time weaving on github. If it's not a problem with your weaver, maybe you can identify the problem by comparison. You can browse it or clone and run it:

git clone git://github.com/zzantozz/testbed.git tmp
cd tmp
mvn -q compile exec:java -Dexec.mainClass=rds.spring.SpringConfigurable \
    -pl spring-aspectj-build-time-weaving

Even using compile time weaving doesn't do the trick, unfortunately. – Naftuli Kay Aug 19 '11 at 04:25
Doesn't do what trick? In my example, the List dependency is correctly populated with both beans of the given type. – Ryan Stewart Aug 19 '11 at 13:00
It doesn't work, even after adding the compile time weaving :( – Naftuli Kay Aug 19 '11 at 17:40
Do you have `` in a context file somewhere? – Ryan Stewart Aug 19 '11 at 18:21

My bad, forgot to implement the requested interface in my abstract superclass. Epic fail. – Naftuli Kay Aug 31 '11 at 22:57
@TK: It always happens where you're not looking :) – Ryan Stewart Sep 01 '11 at 15:37
And it happens even more when you are... \*facepalm\* – Naftuli Kay Sep 01 '11 at 15:49
