--- Comment #22 from jianwu <jianwu at sdsc.edu> ---
My tests show Kepler 2.3 and 2.4 can switch correctly. Basically, users can
switch to 2.4 from 2.3 (either Module Manager.app in 2.3 or Module Manager in
Kepler.app). But if they want to switch back to 2.3, they can only do it in
Kepler.app. Module Manager.app in 2.3 won't work (it won't quit). 

The reason is probably at line 203 of
org/kepler/modulemanager/gui/AvailableModulesPanel.java:
                    System.out.println("AvailableModulesPanel notifiying
shutdown listeners " +
                                "of impending shutdown. Closing any open
databases may take awhile...");
                    ShutdownNotifier.shutdown();

Class ShutdownNotifier is in core module, but suite module-manager-gui-2.3
doesn't have core module. Basically, if the 'current suite' tab in Module
Manager shows the content of module-manager-gui-2.3, it won't quit.

Dan and I tried to have a patch (module-manager-gui-2.3.1) for
module-manager-gui-2.3, Module Manager.app can download it and start from it.
But when Manager.app exits and starts again, it goes back to
module-manager-gui-2.3.0 again.

I think it is very rare that users want to go back to 2.3 after they update
Kepler to be 2.4. If they really want it, the solution could be 1) using
"module manager" in Kepler.app; 2) downloading kepler 2.3 installer; 3) adding
line "core-2.3.^" at the beginning of the modules.txt in
module-manager-gui-2.3.0. (e.g. vi
/Applications/Kepler-2.3/Kepler.app/Contents/Resources/Java/module-manager-gui-2.3.0/module-info/modules.txt).

closing the bug.
