@ ConstructorProperties is a new annotation in Java 6.
http://java.sun.com/javase/6/docs/api/java/beans/ConstructorProperties.html

The most obvious use of this annotation is that it enables XmlEncoder
to automatically encode immutable POJOs as XML (normally, XmlEncoder
can't encode immutable objects without special handling).

The constructor generated by @ Data should automatically add this
annotation. For example,

@ Data
class Point { private final int x, y; }

...becomes...

class Point {
@ ConstructorProperties({"x", "y"})
public Point(int x, int y) {
...
}

Thanks, Jonathan, for submitting this feature request. Looks like a great addition to
Lombok to me.

We've added this feature to 0.9.3 (Burrowing Whale)!

There's still the issue that such a file won't compile on java 1.5, as @ ConstructorProperties is new in java 1.6. It can be suppressed with @ RequiredArgsConstructor(suppressConstructorProperties=true), though we've already deprecated that feature as we intend to remove it once 1.5 fades into the limelight.

Done in commit 5c6fe62

Leaving this issue open until we update the web docs
