Special characters, like < or >, don't need to be escaped in {@code} Javadoc tag (https://reflectoring.io/howto-format-code-snippets-in-javadoc/). Using {@code} improves readability of the Javadoc in code.

Note that this is only possible in inline code blocks because indentation and line breaks are lost with {@code].

It seems checkstyle does not like tags in {@code} blocks, such as {@code <async-supported>true</async-supported>}. This PR is all about that, so may be it should be abandoned.
