Not sure what you mean. The `class+load+cause` log output includes the name before the stack. See the updated examples in this PR's description.

If you mean `class+load+cause` log output precedes `class+load` log output, then yes, that is the case and it's intentional to keep these logging features independent of each other as David suggested (https://github.com/openjdk/jdk/pull/14553#discussion_r1249847278). Since they are independent, it should not matter which output comes first.
