Hi Jie,
The fix appears to directly address the issue of allowing a hostname to
start with a digit. I'm still not convinced that the check will properly
validate the hostname in all cases, but maybe that's a fix for another day:

Please review it.
Thanks.

tests fail with hostnames starting from digits
Hi all,
JBS: https://bugs.openjdk.java.net/browse/JDK-8251031
Webrev: http://cr.openjdk.java.net/~jiefu/8251031/webrev.00/
Some vmTestbase/nsk/monitoring/RuntimeMXBean tests failed in our test
infrastructure.
The reason is that these tests reject hostnames starting with digits.
However, hostnames starting from digits are actually valid according
to RFC1123 [1][2].
It would be better to fix it.
Thanks a lot.
Best regards,
Jie
