RFR 8163083: SocketListeningConnector does not allow invocations with port 0

[JC Beyler]

Hi Daniil,

I noticed a few nits:

http://cr.openjdk.java.net/~dtitov/8163083/webrev.02/test/hotspot/jtreg/vmTestbase/nsk/jdi/ListeningConnector/supportsMultipleConnections/supportsmultipleconnections002.java.html

  -> You have two 2018 in the copyright

http://cr.openjdk.java.net/~dtitov/8163083/webrev.02/src/jdk.jdi/share/classes/com/sun/tools/jdi/SocketListeningConnector.java.udiff.html

 -> Both new methods have an empty line at the start, is that intended?
 -> updateArgumentMapIfRequired: you check the length > 0 but assume
actually it is > 1

http://cr.openjdk.java.net/~dtitov/8163083/webrev.02/src/jdk.jdi/share/classes/com/sun/tools/jdi/GenericListeningConnector.java.udiff.html
  -> Same not sure we need the extra line

Apart from that it looks good to me.

Thanks,
Jc
