        Why is this an issue?

        This rule is meant to be used as a way to track code which is marked as being deprecated. Deprecated code should eventually be removed.

        Noncompliant code example

        class Foo {
          /**
           * @deprecated
           */
          public void foo() {    // Noncompliant
          }
        
          @Deprecated            // Noncompliant
          public void bar() {
          }
        
          public void baz() {    // Compliant
          }
        }
