Hello Todd, You are correct for the support of App Engine Standard with JAR and if you prefer WAR it's understandable. There is a possible workaround here[1] but that's for old Java 7 and I think now 8. There is an old discussion about that here[2]. Deploying it in Flex is the better option. However, there is an explanation here[3], under "What are the changes between the Java 8 and Java 11 standard runtimes?", as to why it's not compatible. It's due to the API. To be future-proof, it might be best to stay with the Flex engine. I understand Standard engine is cheaper, but the API is older.
