When attempting to bump the DAEXIM project to the new odlparent (3.0.x) and yangtools (2.0.x) following https://wiki.opendaylight.org/view/ODL_Root_Parent:BigBumpOfJan2018, as in https://git.opendaylight.org/gerrit/#/c/66431/ (which right now is JUST some POM version bumps, no other changes), then SFT fails with java.lang.ClassNotFoundException: org.junit.runners.model.TestTimedOutException in features/odl-daexim. That exception just means Pax Exam timed out waiting for Karaf (although ideally there should not be a ClassNotFoundException; but that's a minor problem).
If we build the features etc. with -Pq and try it out manually via feature:install odl-daexim then we see that never returns and Karaf spin looping around something (not, technically, dead locked); attached x3 jstack illustrating where it seems to have gotten stuck. There is nothing at all in data/log/karaf.log. This doesn't provide anything more of interest either:
karaf@root()> feature:install --verbose --no-auto-refresh --all-wiring --store resolution.txt --simulate odl-daexim Adding features: odl-daexim/[1.3.0.SNAPSHOT,1.3.0.SNAPSHOT]
FYI: That features/odl-daexim is the one without even restconf, just real basics. (DAEXIM has a restconf-all feature which also includes RESTCONF.)
