Constructor injection example with Lombok

MyComponentImpl.java

/**
 * Sample component implementation showing the usage of constructor injection
 * avoiding the need to declare a constructor by the help of Lombok. There are
 * several advantages of using constructor injection over field injection:
 * 
 * <ol>
 * <li>The class communicates its dependencies. Just start with {@code new 
 * MyDependencyImpl(…}and your IDE will tell you what you need to hand it in. No 
 * need to look into the implementation of the class to discover that.</li>
 * <li>The class can only be used in valid state. The constructor argument require
 * the creator to pass in arguments. Using {@code NonNull} even prevents an accidental
 * {@literal null} being passed in. So no {@code new MyComponentImpl().someMethod()}
 * throwing a {@code NullPointerException} because of a missing dependency.</li>
 * </ol>
 *

not working Java 11

I've updated the gist to rather use the @__ variant. Note, that you don't need any annotation whatsoever to let e.g. Spring instantiate the component properly.
