Adding Energized Smelter recipe

Hi,

With the Mekanism API, there seems to be no way to add Energized Smelter recipes using the RecipeHelper class. I attempted to write a method to do this using Java's reflection:

private static void addEnergizedSmelterRecipe(ItemStack input, ItemStack output) {
    try {
        Class<?> itemInput = Class.forName("mekanism.common.recipe.input.ItemStackInput");
        Class<?> itemOutput = Class.forName("mekanism.common.recipe.output.ItemStackOutput");
        Class<?> recipeEnum = Class.forName("mekanism.common.recipe.RecipeHandler.Recipe");
        Class<?> machineClass = Class.forName("mekanism.common.recipe.machines.MachineRecipe");
        Class<?> recipeClass = Class.forName("mekanism.common.recipe.RecipeHandler");
        Class<?> smeltingClass = Class.forName("mekanism.common.recipe.machines.SmeltingRecipe");

        Constructor<?> inputConstructor = itemInput.getConstructor(ItemStack.class);
        Constructor<?> outputContructor = itemOutput.getConstructor(ItemStack.class);
        Constructor<?> smeltingConstructor = smeltingClass.getConstructor(itemInput, itemOutput);

        Object inputInstance = inputConstructor.newInstance(input);
        Object outputInstance = outputContructor.newInstance(output);
        Object smeltingInstance = smeltingConstructor.newInstance(inputInstance, outputInstance);

        Method m = recipeClass.getMethod("addRecipe", recipeEnum, machineClass);
        m.invoke(null, recipeEnum.getField("ENERGIZED_SMELTER").get(null), smeltingInstance);
    } catch (Exception e) {
        System.err.println("[Mekanism] Error while adding recipe: " + e.getClass() + ": " + e.getMessage());
    }
}

But this causes an exception, which is caught and printed out as:
[Mekanism] Error while adding recipe: class java.lang.ClassNotFoundException: mekanism.common.recipe.input.ItemStackInput

(P.S. my mod is forced to load after Mekanism)

What is the recommended way to add energized smelter recipes/way to fix this problem?

Okay, it took several hours, but I fixed the problem. I had the packages wrong for ItemStackInput/ItemStackOutput. Also, Class.forName("mekanism.common.recipe.RecipeHandler.Recipe") is not the correct way to get a static subclass. It would be, rather, Class.forName("mekanism.common.recipe.RecipeHandler$Recipe").
