How to format code snippet in Javadoc with @ and { symbols inside?

This is what I'm trying to do:

/**
 * <pre>
 * {@code
 * &#64;XmlRootElement
 * public final class Page &#123;
 * &#125;
 * }
 * </pre>
 */

I'm expecting it to be formatted like:

@XmlRootElement
public final class Page {
}

But I'm getting:

@XmlRootElement
public final class Page {
}

Replacing these HTML entities with real symbols (@, {, }) leads to javadoc warnings and absolutely incorrect formatting. What is a workaround?

This is how it finally works for me:

/**
 * <pre>
 * &#64;XmlRootElement
 * public final class Page {
 * }
 * </pre>
