A reduced version:

class JavaBridge(Class)
{
    static if(is(typeof(__traits(getMember, Class, "state")))) {}
    alias T = __traits(getOverloads, Class, "state");
}

class JavaClass(CRTP)
{
    JavaBridge!(CRTP) _javaDBridge;
}

class A : JavaClass!A
{
    State* state;
}

The problem seems to stem from the fact that the first time `State` is analyzed as a type is when the type is requested via `typeof`. In that context, semantic analysis is done with gagged errors, therefore you don't get the user friendly error message. Next time it is analyzed is when traits(overloads) is requested on `state`. By that time the compiler just sees that `state` has an erroneous type but doesn't know the reason.
