java-crate works on vmware but not on aws

Hi all, I'm able to use the java-crate to install oracle jdk on ubuntu 14.04 in vmware. When I run the same to attempt to install oracle jdk on an amazon aws instance (which is also ubuntu 14.04), I get an error: 

   No install method selected for Oracle JDK

I think it's because pallet things the aws instance is redhat, maybe? Is there an easy way to make it think that it's ubuntu/debian instead?
