    [ https://issues.jboss.org/browse/JBIDE-18819?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13022476#comment-13022476 ] 

Fred Bricon commented on JBIDE-18819:
-------------------------------------

The stacktrace shows an error loading the proxywizards in a background job.

The software/update page is loaded in a different job, elsewhere, but the failure doesn't show up anywhere. So yeah swallowed exception is  bad. should at least be logged.

The page should show up, with an error message if no connectors are found (which is a different state than all connectors hidden cause installed)
