This page lists optional manual migration steps what you can do when going to upgrade J2Chrono or ChronoFly version 1.2.x to 1.3.x.

All steps can be performed before or after running the installation.

Remove old Java 7 runtime

Proceed with this step only if you are sure you don't have any application (except J2Chrono or ChronoFly) installed to your operating system that requires this Java 7 runtime installation to be present.

Windows

  • From Windows Apps & features, remove "Java 7 Update 80"
  • Check this directory is not anymore present 
    C:\Program Files (x86)\J2Chrono\jre

Linux

  • Remove directory 
    /usr/lib/jvm/jre1.7.0_80

Upgrade plugins

Since JavaScript plugin engine has been upgraded from Rhino to Nashorn, following change is proposed to be done in every plugin .js file.

  • Add following line to the beginning of plugin .js file 
    load("nashorn:mozilla_compat.js");

Plugin .js files can be found from following directories.

Windows

  • Plugins directory 
    C:\Program Files (x86)\J2Chrono\chromo\plugins

Linux

  • Plugins directory 
    /usr/lib/chromo/plugins
