             Bug #: 52135
           Summary: NotYetConnectedException thrown while remote endpoint
                    is not connected
    Classification: Unclassified
           Product: classpath
           Version: 0.98
            Status: UNCONFIRMED
          Severity: major

        ReportedBy: address@hidden

  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=26582
Simple test server and client

GCC: cross toochain - gcc-4.1.2, uClibc 0.9.28
GNU Classpath 0.98 (and CVS head) + JamVM (git HEAD)

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

   at TestClient.main(TestClient.java:45)

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.
