I took a pass over the changes. I agree its a bit tedious. I'm sure 
there will be a few follow up issues as there are opportunities for 
cleanup in several areas. Just a few comments/questions from a first pass.

ExtendedSocketOption.SO_FLOW_SLA is the Solaris specific socket option 
that was terminally deprecated in 14. The patch removes the 
implementation but leave the API (SO_FLOW_SA and jdk.net.SocketFlow). Do 
you want a someone to take a follow-on issue to remove the API?

ResolverConfigurationImpl.localDomain0 can be removed.

The comment on mcast_join_leave in PlainDatagramSocketImpl.c has a 
residual reference to Solaris.

JISAutoDetect - might be simpler to just initialize EUCJPName to "EUC_JP".

Socket.setTrafficClass(int) swallows exceptions to workaround strange 
behaviour on Solaris. Tracked as JDK-8221487 so okay to leave it to that 
issue if you want. There is also cruft in the old plain SocketImpl that 
to work around eagerness to report "connection reset errors - I think we 
should just leave that because the old socket impl is not used by 
default and will be removed at some point.
