- [`failureMessage`](/en/java/latest/reference/io-github-libtmux-sessioncreation-sessioncreation-failuremessage/) (method): tmux exits 0 even when nothing was created: an explicit {@code -S} under a directory that does not exist prints its own {@code error creating ...} and still returns success, and a binary that is not tmux at all can exit 0 with nothing on stdout the same way {@code run} cannot tell apart from a real session id. Reads tmux's own words when it spoke and names the configured binary when it did not, rather than letting an empty list reach {@code SessionId} and throw an unchecked collection exception with neither in it.
