Java editor doesn't warn about in-statements java annotations

If I write this in the editor, I don't get a warning while I'm coding... but trying to compile with the standard jdk prompts errors.

@Test
    public void someMethod() throws Exception {


        //TODO auto-generated
        @Autowired // editor doesn't warn about anything
        Assert.fail("Not yet implemented");
    }


Is this  a bug or  the desired behaviour? Is it related to support this JSR? http://code.google.com/p/jsr308-langtools/wiki/AnnotationsOnStatements
