Spent several hours troubleshooting 400 responses where lower case values were being parsed by HttpMethod.valueOf(). when used with WebClient.method().

Please either:

• Update the API documentation stating that the method doesn't normalize the value to uppercase.
• In the method, perform a .toUpperCase() before passing it to the switch statement.
• Or thow an IllegalArgumentException when a lower case string is passed.

Sometimes it's the little things that count!

Thank You!
