The machine cannot connect to the Internet directly and needs to be connected to the Internet through a jump machine. The java/net/InetAddress tests report "java.net.UnknownHostException: bugs.openjdk.org: Temporary failure in name resolution" failure do not caused by JVM bug but environmentalk issue, so this PR match the java.net.UnknownHostException and throw jtreg.SkippedException instead of report test fails.
