Contract of @RequestBody(required=true) not obeyed [SPR-11828]

[spring-projects-issues]

Andrei Badea opened SPR-11828 and commented

When I send a HTTP request with an empty body, the respective controller method is invoked with a null argument for the parameter annotated with @RequestBody. Instead, a HttpMessageNotReadableException should be thrown.

This may be a regression introduced by the fix of #14575. Note that fix removed the statement that threw HttpMessageNotReadableException.
