>                 Key: NET-594
>                 URL: https://issues.apache.org/jira/browse/NET-594
>             Project: Commons Net
>          Issue Type: Bug
>          Components: Telnet
>    Affects Versions: 3.4
>         Environment: Windows 7 64bit
>            Reporter: Brad Worrall

> As part of fixing an existing bug Oracle introduced a new bug into FilterOutputStream.close:
> http://bugs.java.com/bugdatabase/view_bug.do?bug_id=8054565
> While the bug is marked as fixed the fix will not be available until Java 9 from what
I can tell and is not in the latest release as of writing (1.8.91)
> This bug can also be reproduced through remote socket closure.
> Due to this bug the TelnetClient when calling disconnect() throws an unhandled exception
and is unable to close the connection, if the socket was remotely closed.
> Stack Trace:
> java.net.SocketException: Socket closed
>         at java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:121)
