I recieved a `Withdrawn` email because the PR is merged by using the GitHub UI instead of using the command `/integrate`. It is good to obey the OpenJDK dev flow and use the command `/integrate` because it would do some checks and avoid the unnecessary/wrong information, such as the `Withdrawn` email.
