MockHttpServletRequest must not throw an exception on getParameter(null) [SPR-10192]

[spring-projects-issues]

Oliver Drotbohm opened SPR-10192 and commented

The JavaDoc of ServletRequest does not specify the parameter name to be a non-null value. So we have to deal with clients calling the method with a null value leniently and simply return null.

Servlet containers like Jetty are not as strict and thus one might stumble over this issue only when using e.g. Spring MVC testing framework.
