Kojo - Unix Release Notes

by lalitplalitp 18 Jan 2013 15:09

  • Kojo has been tested only with Oracle's distribution of Java. If you are using OpenJDK, Kojo should mostly work, but be aware that Kojo has seen very little testing in this environment. Use the Oracle JRE for Kojo if you can.
  • After an upgrade from an earlier version of Kojo, always make sure (via the Help -> About box) that you're running the expected version. If you're not, the older version of Kojo is probably interfering with the new version (this can happen, very rarely, when jar file names change in the Kojo lib directory). In such a case, just uninstall and then reinstall Kojo.
