Doht, I just realised that this change and all changes in org.sonatype.nexus.proxy.maven.routing.internal package UTs are actually not related to NEXUS-5749 but are also cleanup made after MAT inspection, where is seen that these Jetty HTH servers are left running. At the end of UT run, multiple Jetty servers are running, mostly all of the from Automatic Routing UTs...
