This worked fine in the Mars version
of Eclipse (which uses Jetty 9.2.13), but in Neon (which uses Jetty 9.3.9),
I get a configuration exception "Address already in use: bind".
If I remove either the org.eclipse.equinox.http.jetty.http.port or
the org.eclipse.equinox.jetty.https.port JVM arg, then the error goes away
and the remaining port works as expected.
Is this a bug? It seems that Jetty
is using the same internal variable to hold both settings.
