Ryan Smith @ USAA wrote the attached to retrieve the access token in OpenShift using the Java API. He wanted to contribute this and see it added to the client library. Can that happen?

Please let me know when the Java API can be updated to support reading the access token directly. If not, we will need to create a custom overlay jar to add the needed support in our environment.

Thanks,

BTW, Ryan needs this for Conjur v5. He has made the code changes and can share those with whomever is on this.
