EscapedEntity

HTML entities used within @code and @literal tags will be interpreted directly rather than converted to the expected characters. For example, this is wrong:

/**
 * <pre>{@code
 *   &#064;Override
 *   public boolean equals(Object o) {
 *     return false;
 *   }
 * }</pre>
 */

An option is to drop the {@code } tags, though this will then require escaping any generic type parameters which may otherwise be interpreted as HTML. That is, List<Integer> is the text "List" followed by the (non-existent) tag "Integer".

/**
 * <pre>
 *   &#064;Override
 *   public boolean equals(Object o) {
 *     return false;
 *   }
 * </pre>
 */
