注意事项1：java 8只能使用delight-nashorn-sandbox的0.1.x版本，0.2.x版本适用于java 11以上，github上面有讲
注意事项2：打包成springboot fatjar时，需要unpack

理由：

注意事项3：graalvm js的版本不要使用最新的，20.3.5或21.2.0是一个比较稳定的版本，在各操作系统及cpu上都可用。比如arm64
注意事项4：多线程问题，可参考以下文章或demo。
graal javascript thread safety
多线程demo
multithreading
thread issue
async demo
multi threaded java javascript in graalvm
script engine instance problem

注意事项5：graalvm js支持ScriptEngine与Polyglot模式，在delight-graaljs-sandbox沙箱的实现方案中采用的是ScriptEngine，但会面临多线程的问题。按照注意事项4中提到的内容，多线程可以共享graaljs engine，但需使用不同的Context

注意事项6：crash问题，aarch64、openjdk 1.8.0_242会有问题，升级openjdk 1.8.0_332
