Oracle JDK8向け

https://github.com/kkinnear/zprint/blob/1.0.0/appcds

・OpenJDK8で試すと
UseAppCDSが使えないため、効果は少しだけ

appcds-openjdk8.patch

・OpenJDK11

> OpenJDK 64-Bit Server VM warning: Ignoring obsolete option UseAppCDS; AppCDS is automatically enabled

JDK10あたりから、JDK6以前のバイトコードがCDSできなくなってる。
> OpenJDK 64-Bit Server VM warning: Pre JDK 6 class not supported by CDS: 49.0 zprint/main
> Preload Warning: Cannot find zprint/main
> OpenJDK 64-Bit Server VM warning: Pre JDK 6 class not supported by CDS: 49.0 clojure/core__init
