RFR (S): JDK-8250630 JdwpListenTest.java fails on Alpine Linux

[Alex Menkov]

Hi Dmitry,

In general the fix looks good to me.

Some notes:
please update copyright year;

I'd rename compareIPv6Addr to something like isEqualIPv6Addr or 
equalsIPv6Addr;
Also both parameters should be const;

737     // Try to find bind address of preferred address familty first
"familty" -> "family"
