+/**
+ * If put on a parameter, lombok will insert a null-check at the start of the method / constructor's body, throwing a
+ * {@code NullPointerException} with the parameter's name as message. If put on a field, any generated method assigning
+ * a value to this field will also produce these nullchecks.
+ * <p>
+ * Note that any annotation named {@code NonNull} with any casing and any package will result in nullchecks produced for
+ * generated methods (and the annotation will be copied to the getter return type and any parameters of generated methods),
+ * but <em>only</em> this annotation, if present on a parameter, will result in a null check inserted into your otherwise
+ * handwritten method.
+ *
+ * WARNING: If the java community ever does decide on supporting a single {@code @NonNull} annotation (for example via JSR305), then
+ * this annotation will <strong>be deleted</strong> from the lombok package. If the need to update an import statement scares
+ * you, you should use your own annotation named {@code @NonNull} instead of this one.
