Request.getContext().getContextPath()

Description
When I invoke Request.getContextPath(Request) I get back null. The Javadoc does not indicate that the return value may be null and it's not clear what this indicates. Does this imply a context path of "/"? If so, why not return "/"?

A return of null would mean that you are in a handler not wrapped by a ContextHandler.

The default value returned by ContextHandler.ScopedContext#getContextPath is "/".
But if you are not in a context you will instead get the ServerContext which will return null for getContextPath().

Got it. Mentioning this behavior in the method(s)` Javadoc would resolve it for me.

@cowwoc will do. The core handler API in jetty 12 is new in 12 and very much under documented, so feedback like this is most welcome.

@cowwoc see #10297
