The issue we found was not so much Felix - that does indeed run fine on Java 11.
But depending on what packages you really on, some of those that were system
packages in Java 8 but have since move either to separate J9+ modules, or in
some cases dropped completely from J9+ and now need additional bundles. You
can't rely on the system classloader wiring for those in Felix, you have to
make sure the requisite bundles and modules are present.

Wait a minute... if Chuck is having problems running Felix on Java 11 because
of dependencies on the platform, then how is adding MORE bundles by using Karaf
going to help?
Since Felix has been tested on Java 11 and is expected to work, it would be
really good to try to help out with the original problem, as Karl is trying to
do.
