You are aware that notifications are only sent at transaction commit,
right?

Hm. The response to this string (assuming that there's a notify
waiting) would look like
N foo (NOTIFY)C COMMIT (commit command complete)C BEGIN (begin command complete)Z
(ready for new query)
(that's from memory, so forgive any minor inaccuracy). I speculate that
either JDBC or your test code is dropping the NOTIFY in this situation.
