The apprunner.yml file has a supported python and nodejs image for running from source, but by providing a Java installation you should be able to run Java code easily as well. This would be of great benefit to developers who have a hard time rebuilding image's and who want to run in the latest security updates.

Java is supported very well with github actions - you can install Java 8/11/17 (the LTS versions) - so having this as an apprunner base image would be very useful.
