IntelliJ Idea IDE using port 1099

java maven intellij-idea jetty rmi

I'm using IntelliJ Idea Community Edition IDE and I'm trying to run a Maven WebApp with Jetty by command line. I'm on a RedHat box

I run this command:

mvn clean install -P deployJetty -Djetty.port=8083

And I get this error:

Listening for transport dt_socket at address: 5005
Error: Exception thrown by the agent : java.rmi.server.ExportException: Port already in use: 1099; nested exception is: 
    java.net.BindException: Address already in use

The funny thing is that when I close IntelliJ Idea, the 1099 port is released. I can't find the reason why and how Idea is using this port.

Any ideas ? Thank you.

Note: As a workaround, I'm closing Idea, running Jetty and then opening Idea (and I guess forcing it to pick another port)

I am sure Intellij Idea does not use 1099 port internally. I have used this PORT for Tomcat. I would suggest checking if any of idea plugins that you have installed are running on this port. Most of the operating systems can give you the application name that is running on that port.

Eg: lsof -w -n -i tcp:8080 would give me the application running on 8080 on my linux machine.

Hope this helps.
