Question regarding RST packet and the tcp stack

I've been testing out a scenario on windows and linux and I have a question for what FreeBSD does or rfc1122 says: (The code is in java using java.nio)
An application (host) has established a remote connection to another machine. The OS on the host receives the following packets in order for that socket:
Data packet (6 bytes)
At this point the application (host) tries to read from the socket. On windows, this causes a "the os has closed the connection" exception and doesn't let you read those 6 bytes.
On Linux, those 6 bytes can be read.
I've looked over the TCP rfc: http://www.rfc-editor.org/rfc/rfc1122.txt . But it's not clear what should happen to 6 bytes once a RST packet arrives.
Does anyone know what the correct behaviour is? Or point me to freebsd's tcp stack code?
