      Description

      When using a Windows Jenkins slave with an OSX Master (with the slave set up according to https://wiki.jenkins-ci.org/display/JENKINS/Step+by+step+guide+to+set+up+master+and+slave+machines) either disconnecting from the slave side or from the master (by selecting 'disconnect' from Nodes > NodeName), the slave then cannot reconnect until the master jenkins is restarted and an error is shown in the node information. This is extremely inconvenient as it means that the slave machine must be accessed every time the connection is interrupted (eg. a restart of jenkins or master machine). The following stack trace is seen on disconnect:

      Connection was broken
