EasyScheduler-JDK compatibility issue(EasyScheduler-JDK兼容问题)

[zhuwep]

The backend uses the Oracle official JDK1.8 deployment startup (API) error, and can be started normally by switching to OPENJDK1.8.

Exception information:
java.lang.ClassCastException: class jdk.internal.loader.ClassLoaders$AppClassLoader cannot be cast to class java.net.URLClassLoader (jdk.internal.loader.ClassLoaders$AppClassLoader and java.net.URLClassLoader are in module java.base of loader 'bootstrap')

后端使用Oracle官方JDK1.8 部署启动（API）报错，换成OPENJDK1.8可以正常启动

异常信息：
java.lang.ClassCastException: class jdk.internal.loader.ClassLoaders$AppClassLoader cannot be cast to class java.net.URLClassLoader (jdk.internal.loader.ClassLoaders$AppClassLoader and java.net.URLClassLoader are in module java.base of loader 'bootstrap')

It is recommended to explain and prompt to use OPENJDK1.8 in the deployment documentation.

建议在部署文档里说明并提示使用 OPENJDK1.8

We use Oracle official jdk1.8 internally, and open jdk 1.8 in docker. At present, we have not encountered such a problem. We will locate it according to your environment.

我们内部使用的是Oracle官方jdk1.8，docker中使用的是open jdk 1.8，目前没有遇到这样问题，根据你的环境我们定位一下

Magical, but seeing the error message is JDK related, or thank you for your reply.

神奇，但是看报错信息是JDK相关， 还是感谢回复。
