Alright, I'll add it before asking for approval from 7u-dev.

Kurchi,

As you don't plan to use this function outside of net_util.c it's better
to add static keyword as well.

Hi Chris,

Thanks for the additional information.  How about this fix:

Hi,

We are seeing a crash when both libmawt.so and libnet.so are loaded, and
the init()
method in src/share/native/java/net/net_util.c is called, but an init()
method in
libmawt.so gets invoked instead. Although it is difficult to reproduce
the problem,
declaring the init() in net_util.c can resolve the issue.
Thanks Kurchi,

I have seen this, what appears to be a bizarre linking issue, a few
times now over the past year but was unable to get to the bottom of it.

Snipped of a stacktrace and comment from 8005450 ( I was unable to get
the bottom of it, or reproduce ).

This looks like a strange linking issue. Relevant part of the stack
below.
   ...
   C [libmawt.so+0x26c12] init+0x8e;; init+0x8e
   C [libnet.so+0x8b53] NET_SockaddrToInetAddress+0x23;;
NET_SockaddrToInetAddress+0x23
   C [libnet.so+0xc388]
Java_java_net_PlainSocketImpl_socketAccept+0x41c;;
Java_java_net_PlainSocketImpl_socketAccept+0x41c
   j java.net.PlainSocketImpl.socketAccept(Ljava/net/SocketImpl;)V+0
   ...

NET_SockaddrToInetAddress is somehow triggering libmawt init() to be
called. NET_SockaddrToInetAddress does call a local init() function,
that is defined within net_util.c, but it is as if the linker has
decided to call libmawt init().

I think your fix is probably ok, but I wonder if we should air on the
side of caution and maybe give this function a unique name, say
initInetAddrs ( or something similar ).

This low-risk fix will hopefully be going into 7u40.
