Work on 6392818 "Add isDeprecated to javax.lang.model.util.Elements" exposed a regression in javac's handling of deprecation messages:

public class Test {
    public void foo(Foo f) {
@Deprecated String s1 = f.foo;
/** @deprecated */ String s2 = f.foo;
    }
}

class Foo {
    @Deprecated String foo;
}

A deprecation warning is *not* emitted for the use of f.foo to initialize s1. Local variables cannot meaningfully be deprecated so the anntotation should have no effect.
