    [ https://issues.jboss.org/browse/SEAMFORGE-362?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12635058#comment-12635058 ] 

Lincoln Baxter III commented on SEAMFORGE-362:
----------------------------------------------

However, for most plugins, you shouldn't need to restart in order to gain access (it's just that the HTools plugin does not work at all right now.) Again, sorry, working on it.
