    1. It’s not forbidden
    2. It’s not a good practice to instantiate stateless components (like helpers), because you are creating unnecessary instances
    3. All spring beans “live” in the application context, and it is the one that instantiates them, not you. So if you want to be able to inject dependencies into your objects, let them be spring-managed – i.e. don’t instantiate with new.
    4. Typically, only value objects (User, Address, AccountInfo, etc) are instantiated by you (using new)
    5. There is some “magic” that allows you to have both dependency injection and instantiation using new. It is the @Configurable annotation. It uses AspectJ weavers that plug to the VM. But it is not something to consider until there are no alternatives. (the last sentence is my opinion)
