[ https://issues.jboss.org/browse/JBIDE-19738?page=com.atlassian.jira.plugi... ] Martin Malina commented on JBIDE-19738: --------------------------------------- [~rob.stryker], yes, I can replicate Radim's issue and it seems that it happens always. I tried 3 times - twice with JBoss Tools 4.3.0.Beta2 and once with JBDS 9.0.0.Beta2 and each time I could replicate the error window that would just show up and disappear immediately. I followed exactly your steps: 1) enable internet 2) window -> prefs -> jboss runtime detection 3) download 4) Select jboss fsw 6, press next 5) type in credentials 6) accept license, press next 7) disable internet 8) type in proper directories etc 9) perform finish 10) observe error "Host not found" shows up. Except, at the end there was no error window and only an error message in Error Log view: java.net.ConnectException: Network is unreachable An exception stack trace is not available. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
