Q: Daniel: Task<Object> -> Task<?extendsObject>
    A: aha
Well, I wanted that, but unfortunately:
[javac] /home/ceriel/workspace/Saga/src/org/ogf/saga/job/Job.java:21: unexpected type
     [javac] found   : ? extends java.lang.Object
     [javac] required: class or interface without bounds
     [javac] public interface Job extends Task<? extends Object>, Async, AsyncAttributes, Permissions {
