In Head First Servlet and JSP, they have mentioned session and context attributes are not thread safe and only the request attributes are thread safe. So we don't need to synchronize the request object like synchronize the session and context object. If so, my doubt is why request object is synchronised in <jsp:useBean.. scope="request"> page no:348 - chapter - 8 in HFSJ

Let me rephrase my question:
"Is there under any circumstance/necessary to synchronize the request object?"
