SuppressWarningsDeprecated

The problem

To suppress warnings to deprecated methods, you should add the annotation @SuppressWarnings("deprecation") and not @SuppressWarnings("deprecated")

Suppression

Suppress false positives by adding the suppression annotation @SuppressWarnings("SuppressWarningsDeprecated") to the enclosing element.
