the class LambdaFactory method register.

/**
     * Registers a class file transformer together with a factory for creating a lambda expression. It is possible to call this method independently
     * of the class loader's context as the supplied injector makes sure that the manipulated collection is the one that is held by the system class
     * loader.
     *
     * @param classFileTransformer The class file transformer to register.
     * @param classFileFactory     The lambda class file factory to use. This factory must define a visible instance method with the signature
     *                             {@code byte[] make(Object, String, Object, Object, Object, Object, boolean, List, List, Collection}. The arguments provided
     *                             are the invokedynamic call site's lookup object, the lambda method's name, the factory method's type, the lambda method's
     *                             type, the target method's handle, the specialized method type of the lambda expression, a boolean to indicate
     *                             serializability, a list of marker interfaces, a list of additional bridges and a collection of class file transformers to
     *                             apply.
     * @return {@code true} if this is the first registered transformer. This indicates that the {@code LambdaMetafactory} must be instrumented to delegate
     * to this alternative factory.
