Several tcpClient Networking test cases failed during SDP transparent support testing on OEL6 x64 as server and Solaris 11 x64 as client.

The core of the failures is java.net.SocketException with "Invalid argument" message thrown in java.net.SocketOutputStream.write(byte b[], int off, int len) method. It happened in both cases - when Linux was as Server and as client. Below you can find some output on Linux side:

OEL6 x64 as Server and Solaris 11 as Client:

The issue is not reproducible when both client and server are Solaris 11 sun4u. So I guess this is Linux specific issue.
