map list<list<ClassA>> to list<list<ClassB> doesnt work

[Martin Sedláček]

ClassA and ClassB have same fields, but problem lies elsewhere.

When I provide this hint, it creates List<CLassB> instead of List<List<ClassB>>

<mapping>
    <class-a>a</class-a>
    <class-b>b</class-b>
    <field>
        <a>fields</a>
        <b>fields</b>
        <b-hint>ClassB</b-hint>
    </field>
</mapping>

When I provide this hint, it creates List and inside are empty lists, but they should pe populated with ClassB.

<mapping>
    <class-a>a</class-a>
    <class-b>b</class-b>
    <field>
        <a>fields</a>
        <b>fields</b>
        <b-hint>java.util.List</b-hint>
    </field>
</mapping>

Can you provide a github repo with a junit test please showing the problem. Makes it easier to debug.
