出現這個問題的最大原因可能是，目標端口不在netstat 的管理範圍， 所以需要重新設定範圍

Solution for those who can not find the process with netstat -aon command.
Some ports might be reserved by default in various networks. Therefore, if you can not find a :1099 port with netstat -aon command you need to check your reserved ports first.
netsh interface ipv4 show excludedportrange protocol=tcp
Port 1099 might show up as a reserved one in the list. However, it was not the case for me. I decided to try to make an exception for it anyway. It worked!
Follow these steps:
Make sure to copy this text to your notepad, because you will lose internet connection for a moment.
Open your CMD as an administrator.
Write these commands one by one in order to stop your network:
net stop winnat
net stop LanmanWorkstation
net stop WlanSvc
net stop WwanSvc
Exclude port 1099 from a reserved list:
將1099 指定爲你自己的目標檢測端口（要找的端口），一下命令將會以你指定的端口爲起點 (不包括)，連續後四個端口都將從不維護端口列表中剔除
netsh int ipv4 add excludedportrange protocol=tcp startport=1099 numberofports=4
Start your network again:
net start winnat
net start LanmanWorkstation
net start WlanSvc
net start WwanSvc
Done.
Temporary solution.
Simply changing JMX port to 1599 inside of the IntelliJ IDEA also solved this issue for me.
