Bug 105926 [Formatter] Exporting Unnamed profile fails silently
When attempting to export an "Unnamed Profile" from the Project Preferences > Java Code Style > Formatter it will fail silently when it gets to ProfileStore.writeProfilesToStream(): for(final Iterator iter= profiles.iterator(); iter.hasNext();) { final Profile profile= (Profile)iter.next(); if (profile.isProfileToSave()) { final Element profileElement= createProfileElement(profile, document); rootElement.appendChild(profileElement); } } Since the unnamed profile is considered a shared profile and will write an xml file with the content. <?xml version="1.0" encoding="UTF-8"?> <profiles version="8"/> Instead of silently generating an xml file with no content it should rather throw up an error/warning or force a rename dialog. I'll try working on a patch to this respect.
