Annotation literals implementing an annotation interface raise a warning in JBDS

Description of problem:
An annotation literal is a concept defined in Java EE 6, described e.g. in javadoc of http://docs.oracle.com/javaee/6/api/javax/enterprise/util/AnnotationLiteral.html. In this piece of official documentation, an example of usage shows an implementation of an annotation:

public abstract class PayByQualifier
extends AnnotationLiteral<PayBy>
implements PayBy {}

Despite this pattern being defined in the official Java EE documentation, JBDS (Eclipse) warns that annotations should not be used as superinterfaces.

Version-Release number of selected component (if applicable):
WFK 2.3.0.CR1
JBDS 7.0.0.Beta2b

How reproducible:
In a project in JBDS, use the New Annotation Literal wizard to create an Annotation Literal.

Actual results:
A warning is shown, e.g.:
"The annotation type RestRequest should not be used as a superinterface for RestRequestLiteral."

Expected results:
No warning should be displayed as this is an officially endorsed pattern.
