JDK not included in bastion node?

[pierrepgithub]

Trying to run ./provision.sh to deploy the applications but during the OAM step, looks like it's trying to set JAVA_HOME but one doesn't exist on the bastion node? Is this a manual step to install a JDK or should it have been included in the ./provision_oke.sh step when it built the machine and installed the other apps?
