It is using a special jar inside jar classloader, which seems not to 
work well on VMS.

Try unpack the jar file with

jar xvf OpenRocket-15^.03.jar

And then run with:

java  -Xmx800m -cp .:lib/* -Djava.awt.headless=false 
net.sf.openrocket.startup.OpenRocket

I get something to start.

I don't know the program so I can not say how well it is working,
but a GUI opens up where I can chose FILE and QUIT.
