CloudFormation CLI support to generate Java11 resource definitions

I recently initialized a new CloudFormation resource using the Java Plugin, and noticed it auto-generated config/code for Java8.

Since Lambda recently added Java11 runtime support, are there any instructions on how to generate for java 11, or a migration guide?

I am hoping there aren't many changes needed, but want to confirm if there are any plans or already supported solutions for getting set up with Java 11.
