Well, in this case, as the warnings only appear because one of the
"override" JVM options were added, unless you're pushing those
settings to the end-user, they won't see these warnings.

But I do agree with the general gist of it (and what Jochen wrote).
JDK9 seems to be adding (too) many stderr outputs that are on by
default (not limited to jigsaw), and you have to go digging for
specific properties or special -XX JVM flags to set in order to
disable them (if at all possible).
