Currently:

• Karaf integration tests fail with JDK12, and after upgrading to the latest version of Karaf/Pax-exam the build is just stuck
• WF integration tests fail with JDK12, because of https://github.com/jbossas/jboss-classfilewriter/issues/18

It would be nice if we could make these tests pass. Not an absolute requirement, but it'd be nice.
