title: Get parameter value if parameter annotation exists
body: <p>Is it possible to get the value of a parameter if an annotation is present on that parameter?</p>
  
  <p>Given EJB with parameter-level annotations:</p>
  
  <pre><code>public void fooBar(@Foo String a, String b, @Foo String c) {...}
  </code></pre>
  
  <p>And an interceptor:</p>
  
  <pre><code>@AroundInvoke
  public Object doIntercept(InvocationContext context) throws Exception {
      // Get value of parameters that have annotation @Foo
  }
  </code></pre>
