Description
The annotation type java.lang.Deprecated does not have an explicit @Target meta-annotation; therefore, in can be applied in all possible locations even though it is not meaningful in some of those locations.  As part of JSR 308, new locations were added and thereby Deprecated can now appear in still more locations without defined meaning.

EVALUATION Deprecated should be restricted to only be targetable to the set of locations that a missing @Target meant in JDK 5/6.
