Hi,
This change is mainly about clean up of the networking native code.
There are a number of places that cache JNI global references to the
Inet[4|6]Address classes, as well as caching their respective field IDs.
It is also difficult to correctly handle propagation of possible JNI
method invocation failures, from the (get|set)Inet[4|6]Address_XXX methods.
As it happens Inet[4|6]Address.c already makes these classes and field
IDs available [1] [2] [3]. It is then a small matter of ensuring that
they get initialized from any entry point that may use them, in the
various socket/InetAddress/network interface implementation, as well as
NIO and SCTP.
