Comment 2 Tomas Stupka 2015-05-18 16:58:26 UTC 
FileOwnerQuery.getOwner -> ProjectManager.findProjects eventually has to load a project or might block AWT

please evaluate if this has to happen in AWT and in scope of RSMDataObjectAction

canRename(lookup) checks if the file belongs to an open project and is on a source classpath, not much to do there.

For the refactoring action it is not necessary for FileOwnerQuery.getOwner to load projects, returning null would be sufficient.

FOQ isn't expected to return immediately. If there isn't much to do on refactoring side, then feel free to close ...

sounds like an different api. In case the awt canRename() calls from refactoring prove as a significant problem, please file an issue to cover the requested enhancement.
