Previously, we used to first call `released()` on the old exchange and `cancel()` the new exchange, before setting the `this.exchange` to the new exchange. Now, with this change, we first switch the `this.exchange` to the new exchange and then call `released()` and `cancel()`. Do you think that could have any (odd) issues? ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/14038#discussion_r1203930954
