Arne, thanks*1E+06!

I unpacked the .JAR as you suggested and then, I executed using your long ...

 "java .... net.sf.openrocket.startup.OpenRocket"

command.  The thing puked up a lengthy morass of error messages and tracing
info and terminated with:

%DEBUGBOOT-W-EXPGFLQUOTA, exceeded pagefile quota
%CMA-F-EXIT_THREAD, current thread has been requested to exit

I didn't see any such error message(s) previously!

I increased the account's PGFLQUOTA to 2,000,000 and executed your command
again.  OpenRocket eventually fired up.

I then went back and tried:

$ java -Xmx800m -Djava.awt.headless=false -jar OpenRocket-15^.03.jar

OpenRocket fired up and even faster too.  I suppose I can now free up some
of that disk that contains everything that I'd extracted.

This is great news because I can now just take my Android tablet out to the
launch field instead of lugging my Linux laptop should I need to simulate a
flight because I can now ssh into my home system and run this.
