011 * The <code>PostConstruct</code> annotation is used on a method that needs to be executed
012 * after dependency injection is done to perform any initialization.
013 * <p>
014 * Note that we can equally use any <code>PostConstruct</code> annotation - so we can use
015 * the one from <code>javax.annotation</code>, <code>jakarta.annotation</code> or this one.
016 * </p>
017 * <p>
018 * Only one method in a given class can be annotated with this annotation.
019 * <p>
020 * The method on which the <code>PostConstruct</code> annotation is applied must fulfill
021 * the following criteria:
022 * <ul>
023 * <li>The method must not have any parameters.</li>
024 * <li>The method may be public, protected or package private.</li>
025 * <li>The method must not be static.</li>
