Thanks Mark!
You might also want to look at r1809434 as a candidate and check whether
that workaround looks OK for you.
Wishing you a nice and successful TomcatCon!

Hi all,
when running TC 8.5.21 (9.0 should be the same) with Java 9 I get the
following warnings on STDOUT during shutdown:
Tomcat 9 has the Java 9 fixes. 8.5.x doesn't. I've put together a list
of the Java 9 commits that need to be back-ported. Now that Java 9 is
final those back-ports need to happen.
This is on my TODO list for after TomcatCon London on Tuesday.
