Sorry for the delay getting back to you on this. 

To me knowledge, we've never documented the JVM_* functions and there 
shouldn't be customers or applications using these functions to call 
into the VM. In the libraries there isn't any reason for us to be using 
the JVM_* socket functions on Windows so it doesn't matter if there is 
an implementation or not. The dependency on the JVM_* socket functions 
was removed from the Windows code back in jdk1.4. Once jdk8 opens for 
business then we can remove the dependency from the Solaris/Linux code 
too but we can't remove the sockets functions from HotSpot as they will 
continue to be used when the VM is combined with older JDKs.
