RSSOwlnix is a fork of RSSOwl a powerful application to organize, search and read your RSS, RDF & Atom news feeds in a comfortable way. Highlights are saved searches, notifications, filters, fast fulltext search and a flexible, clean user interface.
the SWTError appears when one tries to start rssowl with the wrong jre and it fails (jre version too old or wrong arch (32bit rssowlnix but 64bit jre = Java was started but returned exit code 13))(used jre 1.8.161 32bit). afterwards the home folder %userprofile%.rssowlnix-beta is messed up so that even the rssowlnix 64bit version (jre 1.8.181 64bit) does not start anymore giving the same error.
fixed by renaming the folder %userprofile%.rssowlnix-beta\config so it can be recreated.
alternativly starting rssowlnix 64bit version with java 10.0.2 also fixes it (maybe the change of the jre major and minor version causes some reinitialization?)
