Re: [tycho-user] shipping directly a jre with an eclipse product on OSX

[laeubi@xxxxxxxxxxxxxx]

If i rememmber right from last time digging into Equinox source 
"restart" does not really restarts the process but exit the application 
with a special statuscode and the instantly start up the OSGi-Framework 
again (switch workspace works in a similar way).

So I think updating a JRE/JDK of a running product won't work as 
expected without additional support for this specific use-case because 
the JVM never exit but required files are already deleted.

The only reliable way for such upgrade-path I see is using the director 
application and modifying a (non-running) install.

It might also work to install the new feature, then SHUTDOWN and then 
uninstall the old one.
