这就是我目前所做的：

1. I have deployed a java 11 application on aws fargate and it is up and running.
2. Task definition is correctly configured for tcp port mapping to application port 
   and jmx port (3939).
3. There is VPC configuration which allows communication between my network and aws.
4. Application is started with these additional system properties for 
   remote jmx connections:

   -Dcom.sun.management.jmxremote.port=3939
   -Dcom.sun.management.jmxremote.ssl=false 
   -Dcom.sun.management.jmxremote.authenticate=false

5. From my local machine I am successfully able to telnet to private IP of fargate task 
   and jmx port 3939.

但是当我尝试使用jvisualvm或jdk任务控制连接到jmx时，它无法连接。我是不是漏了什么？
