Reports attempts to reflectively check for the presence of a non-runtime annotation.
|
|
<p>Using <code>Class.isAnnotationPresent()</code> to test for an annotation
|
|
whose retention policy is set to <code>SOURCE</code> or <code>CLASS</code>
|
|
(the default) will always have a negative result. This mistake is easy to overlook.</p>
|
|
<p><b>Example:</b></p>
|
|
<pre><code>
|
|
{
|
|
getClass().isAnnotationPresent(SourceAnnotation.class); //always false
|
|
}
|
|
|
|
@Retention(RetentionPolicy.SOURCE)
|
|
@interface SourceAnnotation {}
|
|
</code></pre>
