[Viacheslav Kabanovich (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-21463?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13166665#comment-13166665 ] 

Viacheslav Kabanovich commented on JBIDE-21463:
-----------------------------------------------

IPortForwardable.forwardPorts() completes and after that IPortForwardable.isForwarding() returns true. 
UI updates its state by checking this boolean, then it seems that IPortForwardable.isForwarding() should return false for the failure.
Implementation in restclient in forwardPorts() starts a process  with command 'oc' and in isForwarding() it checks if the process is still alive. So, it seems that at port-forwarding to a used port the process keeps to be alive and some other means are needed to see that it failed.
