I'm using Netbeans 7.2 beta. The ability to detect unused "use" statements is a great new feature, but it has this problem:

Many times, I'll "use" a class as an doc-comment annotation; this is very common in frameworks like Symfony2 and Doctrine. For example:

use JMS\SecurityExtraBundle\Annotation\Secure;

class MyController
{
    /**
     * @Secure(roles="ROLE_ADMIN")
     *  This annotation requires that "Secure" be imported as above.
     */
    public function myAction() { }
}

In this example, the @Secure annotation will not work unless the class is imported, but Netbeans marks the "use" statement as unused.
