I have a requirement to launch a second Java app from within my RCP app.
I've tried two sort of standard ways of doing this and neither is
satisfactory:
* If I call the second applications main() method and then the user closes
that application it crashes the RCP app, too (presumably since they run in
the same process)
* If I use Runtime.getRuntime().exec(java blahBlahBlah) I lose the ability
to close the second application programmatically from within the RCP app,
which is a requirement.
What I'd like is to do what the JDT does where you can both launch and exit
an application from RCP, but I don't want to include the JDT as a plugin and
have all the launch configuration stuff contributed to my RCP app. I've
been rooting around in the Eclipse source code for a while but haven't been
able to figure out how this is accomplished. Can anyone offer a suggestion
or point me in the right direction?
TIA!

Actually, at least one way that JDT launches java is to use
Runtime#exec() and then kill the Process like this (from RuntimeProcess
in org.eclipse.debug.core):
Process process = getSystemProcess();
if (process != null) {
process.destroy();
}
I've also followed up to JDT, which controls the launch configurations.
Later,
