[JBoss JIRA] (JBREM-1307) TimedOutputStream OutputTimerTask call to close on SSL OutputStream blocks
by Ron Sigal (JIRA)

> Project: JBoss Remoting
> Issue Type: Bug
> Security Level: Public(Everyone can see)
> Components: transport

> In order to provide a mechanism for timing out a network/socket write operation, the org.jboss.remoting.transport.socket.TimedOutputStream class starts a timer. If the duration of the write operation exceeds the timer interval, then the timer will call close() on the output stream. This interrupts the output stream write() operation and causes the write operation to throw an IOException.
> When the output stream uses secure sockets (SSL), however, the call to close() on the output stream can block indefinitely. The threads associated with the write() and close() operation will only clear when the tcp keepalive timeout mechanism in the operation system is invoked.
> This appears to be related to a know bug in the java runtime: http://bugs.sun.com/view_bug.do?bug_id=6358629
> Specifically, in a thread dump you will see:
