In our Eclipse based project, we requires somes dependencies feature
(like CDO) and these dependencies includes somes plugins which
contributes "org.eclipse.ui.popupMenus" extensions to our CNF based
view, we would like to hide these contributions or find a better mean
than "org.eclipse.ui.popupMenus" extension point to have popupMenus
contributions hideable. Do you know a way to hide these contributions?
