The machine cannot connect to the Internet directly and needs to be connected to the Internet through a jump machine. The sun/management/jdp tests report "java.net.SocketException: No such device" failure do not caused by JVM bug but environmentalk issue, so this PR match the output and throw `jtreg.SkippedException` instead of report test fails.

Something else isn't right if you are getting this error so I think further investigation is required to see if the issue is the test choosing the wrong interface or address, or a configuration issue on the test system.
