当前 Java JDK版本和家庭环境变量命令行输出：
D:\>set
JAVA_HOME=C:\Program Files\Java\jdk1.8.0_161
如何解决自定义Jira插件中的错误？
我检查过，Java SDK已经包含此类，所以这是一个奇怪的问题。
j2ee 1.2.1 jar修复了启动问题，但中断了Java代码中的getConnection（）调用
Caused by: java.lang.ClassCastException: sun.management.MemoryImpl cannot be cast to javax.management.NotificationEmitter
这是我的整个根 POM XML文件内容，
它仅包含olugin框架和oracle，postgres，mysql，mssql和相关的依赖项：
