The telentclient is leaving the connection even after calling the disconnect properly.

           Summary: The telentclient is leaving the connection even after
                    calling the disconnect properly.
           Product: Commons
           Version: 1.1.0
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: Major
          Priority: Other
         Component: Net
        AssignedTo: commons-dev@jakarta.apache.org
        ReportedBy: knandipati@s-square.net
                CC: knandipati@s-square.net


The TelnetClient module of commons/net is leaving the connection on the server 
open even after the disconnect() is called properly. This is happening only on 
Linux but not on solaris. I am using redhat Linux 8.0 on Intel xeon. Kernel 
version 2.4.20-20.8smp.

Temporarly we are sending exit to the telnet shell, which is clearing the 
connection, but causing the null pointer exception.

Please help on this. This problem is there in 1.0.0. Recenly we downloaded 
1.1.0. this new version also has the same problem on linux. I am not sure, 
this bug is related to linux or commons-net.

Thank you for your help
