[jboss-jira] [JBoss JIRA] (AS7-1833) CLI usability: operation :shutdown results in "Communication error"

[Alexey Loubyansky (JIRA)]

    [ https://issues.jboss.org/browse/AS7-1833?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12673661#comment-12673661 ] 

Alexey Loubyansky commented on AS7-1833:
----------------------------------------

The communication error is out of date now. But now there is another issue, we don't have a notion of "connection closed" event and the cli remains in the "connected" state. And if a user tries to communicate with the controller it will be hanging for the "time out" amount of time.
So, we need some connection status checking api/notifications to handle this better.
And also take into account :reload and automatic re-connection (if we want to support that).

> If you shutdown the server, you get an error:
> {code}
> [standalone at localhost:9999 /] :shutdown
> Communication error: Channel closed
> Closed connection to localhost:9999
> {code}
> Even though its considered by this comment clean - https://issues.jboss.org/browse/AS7-689?focusedCommentId=12614756&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-12614756 - I is not really clean as you get an error but termination of the channel can be anticipated. Users might be confused now knowing if its an actual error or not. For example take a look at SSH.
