Rocket serialization compiler does not allow for List interface to be used. I suspect it doesn't allow any of the collection interfaces, such as Map, Set, etc.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a class like the following:
public class TestListInRocket implements Serializable {
    private static final long serialVersionUID = 1L;

    protected List<Integer> testList = new ArrayList<Integer>();

    public TestListInRocket() {
    }

    public List<Integer> getTestList() {
        return testList;
    }

    public void setTestList(List<Integer> testList) {
        this.testList.clear();
        this.testList.addAll(testList);
    }

}

2. Add the following to your serialization factory interface.
@serialization-listElementType java.land.Integer
@serialization-readableTypes 
com.gwtblocks.client.serialization.rocket.TestListInRocket
@serialization-writableTypes 
com.gwtblocks.client.serialization.rocket.TestListInRocket

3. Try to compile the code with gwt and you get compilation errors.  If I 
change the List<Integer> definition to use a specific type of list 
instead, such as ArrayList<Integer>, then it compiles just fine.

What is the expected output? What do you see instead?
I expect the compiler to not have any problems compiling the code.  
Instead I get the following errors:
