[jbosstools-issues] [JBoss JIRA] (JBIDE-17624) (un)checking Early Access while refreshing the connector logs an org.eclipse.swt.SWTException

[Mickael Istria (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-17624?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12981046#comment-12981046 ] 

Mickael Istria commented on JBIDE-17624:
----------------------------------------

I guess it may be a difference between how SWT handles graphical resources between Linux/GTK and other OS. Since both Windows and OSX are affected, it's most probably in Central code which happens to work on GTK "by luck".
When UI is refreshing, the "layout" shouldn't be called.
