Symptoms

I am installing O2A Cartridges for 7.2.4.1 applications but when running the command to encrypt passwords ( ant create-osm-admin-server-xmlie-encrypted-password-properties-file ), I receive the following error:

This might seem that it needs Java 1.7.

I have the following:
  - build.properties: jdk.home=C:\Program Files\Java\jdk1.7.0_75
  - Path: I have Java 1.7. set In Environment Variables(please see attachment)
