Using netbeans 7.2 RC1,

netbeans reports unused use statements, but if statements are aliased and used in doctrine annotations they are still highlighted yellow as unused.

ex.:

use Doctrine\ORM\Mapping as ORM;

/**
	 *
	 * @var \SCMS\Entity\AdminRole
	 * @ORM\ManyToOne(targetEntity="AdminRole", inversedBy="admins", cascade={"persist"}, fetch="EAGER")
	 * @ORM\JoinColumn(name="role_id", referencedColumnName="id", onDelete="RESTRICT")
	 */
	protected $role;

here ORM is used as @ORM\ManyToOne, but reported as unsed use statement at the top of class file.
