The 'NotYetConnectedException' is thrown if the remote endpoint closes the connection. Reproducible using the attached testcase:

java TestServer
ONE
TWO
THREE
BYE

java TestClient
Sending: ONE
Sending: TWO
Sending: THREE
Sending: BYE
Sending: FOUR

Java_gnu_java_nio_VMChannel_getpeername function returns 0 due to getpeername returning -1. SocketChannelImpl class isConnected is calling getpeername every time! I think it should buffer the connection state during connect() instead.
