repotools set-up of JTS always crashes with a NullPointerException

I'm trying to generate a response file so I can automate the configuration of CLM post installation on centos. To do this I use the following command:

./repotools-jts.sh -setup repositoryURL=https://<blanked>:9443/jts parametersFile=m.txt responseFile=respjts.txt prompt=missing adminUserId=<blanked> adminPassword=<blanked>

All goes well each time I do this until I get to the licensing section. No matter what license type or even if I select no license repotools crashes at this point:

 Choose an option:
  [1] I accept the terms in the license agreement.
  [2] I do not accept the terms in the license agreement. - default
 ?

I have tried the same action interactively on the browser and it works fine. But I can't get it to work on repotools does anyone have any ideas how I can fix this as I'm stuck?
