EDIT

updated version in pom file to 7.4.4 and replaced usage of org.json with elemental.json
Two issues seen (needs more investigation) :

• org.eclipse.jetty.io.EofException seen when accessing UI using jetty 9.0.0 M3 included in run-jetty-run (nightly)
• d3 tree in concept relationship editor is really : could be due to change to elemental
