The following code in RepositoryId.createForAnyType():

        if (type.isArray())
            return createSequenceRepID(type);
        else if (/*(!isRMIIDLType(type)) &&*/
        IDLEntity.class.isAssignableFrom(type))
        {
            try{
           return get_instance_of_helper(type).get_id();
            }
            catch(Throwable t) {
           return createForIDLType(type, 1, 0);
            }

        is not returning the correct repid for some IDLEntity types that are not
        valuetypes. This is because the get_instance_of_helper() method returns
        a ValueHelper instance. For non-valuetype helpers, there is no such
        thing, so this method throws an exception. The logic catches this and
        calls createforIDLType, but this does not return the correct repid if a
        #pragma prefix was used in the original IDL.
