As I mentioned before, you if you pass "-help" or "-showversion" in the creation of the IBM or Sun VM you will get an error, e.g.: C:\temp\sample>test JVMJ9VM007E Command-line option unrecognised: -help Failed to create VM with rc=-6. These command-line flags are handled by the launcher (not the VM). Since in Harmony there is not a 1:1 correlation of launcher to VM implementation you will have to either print out generic help in the launcher (bad) or go for an extension to the VM interface to get/print help text. I believe that you could write a useful generic implementation of version info since VMs put that into system properties.
