Jtreg build is failing

[Stuart Monteith]

Hi,
 I just noticed I have hit this problem.

HelpTree in jtharness-5.0.jar has this:
  private java.util.Comparator nodeComparator;
Whereas in jtharness-4.6.jar it has:
  private static java.util.Comparator nodeComparator;

i.e. the nodeComparator field is no longer a static field.

This happened since adopt-openjdk started building with this:
    https://adopt-openjdk.ci.cloudbees.com/job/jtharness/lastSuccessfulBuild/artifact/jtharness-5.0.tar.gz

BR,
  Stuart
